Hiking (uphill) 2:35:00 
Tucson mountains. Hugh Norris trail, up to Wasson Mountain. Right knee and right Achilles hill make themselves known but not debilitating.
Beautiful trail, a bit posh. (Granite risers installed for the first mile.) Gorgeous desert garden the whole way.
At the beginning of the trail a sign warned that Africanized bees were in the area, and to stay away from them. So much for all my effort to avoid them by not doing Tanque Verde yesterday. I made a mental note to run like hell back toward the trailhead if I saw any bees.
Came upon a roadrunner at mile 4. Roadrunner didn't run, but did stay on the path and kind of led me on. At first I was real still and quiet. After a while I got bored and walked right up to the critter, and stopped a couple feet away. When he didn't move, I started a conversation. He turned his back to the sun and fluffed his feathers. Eventually I nudged past.
At the top of the mountain I started in on my lunch and book. There were a couple flies, fine, but then there was a bee so I panicked and got the heck out of there. I figured it must be the Superdome escapee.
Read about the 2004 discovery/creation of elements 113 and 115. And about Einstein being into magnetism.
Hiking (downhill) 2:05:00 
I read an article speculating about whether life could be based on something other than C/H/O and swim in something other than H2O.
After the hike, went out with Matt who is featured on the front page of today's Arizona Daily Wildcat for discovering that a toxin gene laterally transferred between brown recluse spiders and some nasty bacteria. We decided to skip an evolution lecture on campus and instead head for the neighborhood restaurant/bar where three different people commented independently to Matt about the article. It's funny that the picture of Matt has a title above it, "The Missing Link." Matt made monkey sounds over his beer.
