Did I mention how much I like Austin?

Coffee on the porch - at a comfortable 71F - is a big change down here. Thanks to fairly persistent rain over the last week, this fairy-land scene greeted us amidst the Scotch Bonnet pepper plant stalks. It looked like an elf would pop out from underneath. From the Rogers Mushrooms website the closest match I see is Leucocoprinus birnbaumii in this picture link.


This mushroom presaged a very nice day. After a 3+ mile walk we headed off again to Hill's Cafe for the gospel brunch. Hill's is a South Austin institution. There is a long tradition of music here, as well as good food.


Today's offering was Danny Brooks.


This site has a lot of history, as it used to be the Travis Country Court House. The state seal shows up on the floor as you walk in.










After being seated in the Willy Nelson booth (with a photo signed by Willy himself), we were treated to more really good music. Mr. Brooks had a great voice, with a lot of soul and the ability to really belt. His small combo (drummer not seen here) consisted of really good musicians. The repertoire varied from gospel to country to talking blues (backed by a reggae style backbeat). The highlight of the day was an older gentleman getting up and doing an old-time dance. The band added a a few bars to the end, they enjoyed it so much.

This kind of music makes me very glad and very sad. Glad that I am hearing it, sad that I am not making it.


Thanks to Mr. Brooks and company for a marvelous morning.


Today was also the day of the Pecan Street Festival. It is held on 6th street in downtown Austin. Parking is hard to find. We were lucky to find a spot 5 blocks away. As we approached, we found some of Austin's alternate transportation modes.






For me the story is usually not the booths. There is just too much repetition there. This festival spans several intersecting streets. At the end of each intersecting block there was a different band. These guys had an interesting mix of American-style ska (originally a Jamaican music style), with a mix of big band. It was strange, but infectious.


It's great to see young musicians jamming up a storm and enjoying themselves so much.


There was a great mix of people, as well. Great big biker guys walked alongside families with strollers. Older folks, teenagers, and toddlers watched street performers of various types.


We were so full of breakfast that the varied food offerings never had a chance, despite smelling wonderful.


A bit of Austin weirdness and we were off to the car. You should have seen this guy's pointed toe boots!


4 blocks past the landmark Driskill Hotel we were back at the car. More about the Driskill another time.

Facebook was down today

Apparently Qwest was experiencing difficulties that lead to Facebook being unavailable to many people. Early in the design of the Internet, the TCP/IP layer was designed to deliver packets by many different routes. It was designed to be failure-tolerant so that this type of thing would not happen for this type of reason.

Soooooo, how/when did we engineer ourselves into a spot where that basic design tenet does not work? I don't really give a healthy RA about Facebook being down. I do give an RA about things working as designed.

Footnote: Programmer screw-up caused the problem, not design failure. Better, in a way, but not good.

Old people give most honest advice (also, harshest) - via Boing Boing

I did not know this! Older people tend to lose their "executive functions", the ability to control impulses in response to stimuli. Among the executive functions are the ability to control inappropriate actions. There are at least five types of situations (see the Wikipedia link above) that require non-routine responses.

  1. Those that involve planning or decision making.
  2. Those that involve error correction or troubleshooting.
  3. Situations where responses are not well-rehearsed or contain novel sequences of actions.
  4. Dangerous or technically difficult situations.
  5. Situations that require the overcoming of a strong habitual response or resisting temptation.
In losing their executive functions, however, older people apparently become more honest, and sometimes hurtful, in their response  Older people will sometimes call fat people fat and suggest they exercise or eat less. Younger people don't do that.


As usual with social sciences, there is no way in the world to control enough variables to draw any useful conclusions. The first three comments for this Scientific American article really rock!

  1. Could it not be that older folks no longer care for the social "niceties?" They know there are no significant social downsides to honest responses at their stage of life.
  2. Grandma is independently wealthy and she won't hold her tongue. Were she broke she'd worry that someday you'd put her in that home she saw on 60 minutes.
  3. Or maybe it's because the old folk have more insight, (been there, done it, got the T shirt, got the scars) and more importantly, have the wisdom and experience to give better advice? I should know, I'm really,really old...
Quod erat whuuuut?

I must be getting older; and visiting Dad

During this last trip I seemed to get exhausted each day with just plain driving. I didn't notice it until we stopped, but then I needed a nap. We were only driving about 6 hours per day, usually.

We were in the Trumansburg area for 3 days and part of another day this trip. We found Dad in fine fettle. He will be 89 next month, and has the curiosity of a young person. He reads, listens to the news, and comments on current events with conviction. :-) His energy and activity were better than we have seen in the last couple of trips. We spent hours driving around the area, with Dad contributing stories about people he knew (more and more stories seem to be about people who have left the scene).

One day we went on a wild goose chase looking for a chainsaw that had not been fixed. Dad no longer runs it, but does supply parts and fixes. We drove all over between Cayuga and Seneca Lakes just taking random corners at his direction, chasing stories down the road.

One day we took off to Ithaca for a doctor's appointment, then stopped in a Chinese grocery to get Dad some green tea. He drinks it like water all morning. One box of gunpowder tea - $8.99. There we also found lon ngan (Bower romanization). These are dragon's eye fruits, something like li chee, but not really. The lady at the register was happy I asked her about them. They are only available once a year. You peel them, removing a thin, stiff skin and exposing a jelly-like, sweet, mild flavored fruit. There is a pea-sized pit inside, so be careful if you get some!

Then we went off to Enfield Glen (Robert Treman State Park). I had not been for years. Cornell University used to have a Physics Department picnic there every year. For us country kids it was a real treat. There was soda pop (we never had it at home) - mmmmm, grape. There was square dancing, soft ball, hiking, volley ball, and just plain wiggling, followed by a dish to pass supper. Physicists know how to have a good time! We always celebrated the windy downhill part of the road as being the last stage of the picnic journey.

This trip we passed through a newish gate on the walk up to the falls.


Dad lead us past the bath house up toward the dam and the falls. There is a lot of stone work in all of these state parks. During the Civilian Conservation Corps (CCC) days, this was the only work available for many people. CCC was part of Roosevelt's New Deal, saving many from desperation during the depression days in the 1930's. The Finger Lakes benefited greatly.


The swimming area is beautiful, even with the dam opened and the pool drained. Back in ancient history I was called here to lifeguard once. Most of my guarding time was spent at Taughannock Falls State Park.


The falls itself is kind of typical of the area, shale layers providing a cascade. This time of year is usually fairly dry until the fall rains come. (They arrived during our visit.)


Many of these State Parks have lovely stone building like this.


Weather had taken a coolish turn by the time we arrived (60F or so). Even so, these hardy bees were at work on goldenrod and other late flowers.


We took a parting picture of the spot where the road dips through the creek. We always loved driving through this part, so we did again.


Nobody wanted to climb the glen (lots of stone steps and waterfalls, and big climbs), as we had only one car. So we drove on past the wiggly parts of the road and parked at the top of the park (several miles away), near the old mill. There were lots of interpretive signs here, but Dad supplied his own narrative as well.

Apparently his great uncle owned a mill on Taughannock Creek (many years ago). When Dad and John Duddleston were young, they used to invade the mill, with his uncle chasing them from floor to floor. Eventually, the state of New York purchased the mill, just before the Flood of 1935. The deal closed a week before the flood, which then came along and wiped out the mill.

Here you can see some of the wooden teeth on the main wheel of the Enfield Glen mill.


We had been here many times before, but this time I had a camera.


Here is the pit where the millrace entered. You can just see the dark hole on the far side.


The impellor sits down in the pit on the opposite side. It is detached here from the shaft to the right.


The gear on the shaft was the main driver, with a series of reduction gears taming the motion for the millstones.


All the power for this mill came from this small creek.


We had time for a couple more days, one day driving through Watkins Glen during its preparations for the Vintage Grand Prix parade. We just missed it, but saw a cabillion convertible sports cars as we drove through. After getting a replacement for Dad's thousand year old microwave, we took a long hike down to Seneca Lake (at the old Boy Scout camp). Dad and I both wheezed our way successfully up the hill on the return trip. He gets along very well for an 89 year old. I was quite happy BH (better half) and I had been walking daily down in Austin.

A dinner in Sheldrake at Kidder's Landing finished up the trip. Sheldrake is a gorgeous place mid-lake on Cayuga Lake's western side. It houses beautiful Victorian mansions and several restaurants. We sat outside and watched the sunset along the lake. A bit of ice cream at Cayuga Lake Creamery (voted New York's best), a snooze, and we were on our way on the next leg of our journey.

Panama Rocks

Near Jamestown, NY (on Lake Chautaugua is a small, privately owned park called Panama Rocks. It sits in a beautiful setting on a hillside in western New York. The park charges a modest admission fee to view some spectacular rock formations.


A mile long trail quickly provides a view of the cracks and fissures that fill the site.


Lots of beautiful, old growth trees shade the site. Their roots are everywhere. The park requires that visitors sign a waiver, as the trail can be a bit difficult.


The guide map provides a list of the 15 or so named formations. On the downhill portion of the trail you quickly begin to see why this site is so special.


Ancient rocks laid down by a primordial sea mix with relatively modern trees to make a fascinating set of views.


There is a kind of rain forest feel to the place. It is cool and damp, and moss grows everywhere. The cracks and fissures are endless and complex.


Shade and sun are at battle here. Brighter spots peek through darker.


Some shallow caves are in evidence.


There is no sign of anything much larger than chipmunks, though.


Some of the rocks make you wonder.


As you climb to the upper part of the trail you begin to look down into cracks instead of up.


Pay attention here! You will want to see what is down each chute rather than be down the chute.


This is a great place for nature lovers and people curious about rocks.

On the shore of Lake Erie

One of our stops on the way to the Finger Lakes was on the shore of Lake Erie. Thanks to Google Maps we found a small motel right on the shore. The reception was warm and friendly.


Sitting on a bluff some tens of feet above the shore, the Lakeview provides a peaceful setting for tired travelers.


A steep stair down the hillside let us see the shore directly.



The local guidebook in the motel lead us to the Crazy Parrot, a local restaurant above a marina. The drinks were colorful.


The view from our outdoor table was beautiful as the sun set over Lake Erie.


In the morning we left our enjoyable setting for the last leg of this part of our trip.

Along the road

We spent the last few days driving up from Texas to New York to see Dad and my family. Along the way we took a few hours off to visit Mammoth Cave. Thanks to BH (Better Half), who spotted our proximity while on the road. We had no idea how huge this park was until we drove in from the interstate. It goes on for miles and miles. As we arrived at the site we despaired a bit. The parking lots were both huge and full. The visitor center made clear that the guided tours were pretty full for the day, so we opted for a self-guided tour. It was enough, as it turned out.


After a brief walk down a shady path we reached the cave entrance. A Park Service guide gave us a brief introduction, then we started down. At the top of the stairs it felt like an air conditioner was in place. Cool air blowing up from the opening enveloped us. It felt great, given the warmth of the day.


The self-guided tour is in a pretty pedestrian part of the cave. Some of the walkway is paved, some is a slightly uneven natural surface.


During the War of 1812, this cave served as a source of saltpeter (Potassium Nitrate), the oxidizer in the gunpowder of the time. The war and associated blockade had cut off supplies from abroad. You can just make out the works here (not enough light from my flash to do it justice.) The nitrate was washed out of the materials as a Calcium salt, then Potassium was substituted. The trade ceased quickly when the war ended, as saltpeter from bat guano and other sources again became available.


We spent a bit of time down the hole, then looked for daylight again.


We spent some time walking down to the spot where the Green River emerges from a spring coming out of the cave.


The area seemed rife with butterflies. This one caught our eyes on  one of the interpretive signs. From the side it looked like a dry leaf.










Down in the bottom, where their feet are wet, was a large stand of ancient Sycamore trees. Here BH provided an idea of their huge size.


In the midst of a significant climb back to the parking lot, BH found a refuge in an old hulk.


As we were climbing (and I was wheezing), we came on a group of three young guys loafing at a bend in the path. I was about to make fun of them for letting old farts come up on them when they bounded straight up the hillside. They wanted no part of the switchback path, quickly putting a couple hundred feet of altitude between us.

Back at the parking lot we took sight of this more typical butterfly. Then we were off to finish the day's travels.
