Pima Canyon trail.
I told Peg last night that I was planning on doing the Tanque Verde Trail (nice mostly ridge walk on the east side of Tucson). She mentioned that Africanized bees had been seen there. Upon further questioning, she described in detail a case where a lady died on her front lawn attacked by these bees (in Tucson but not on the Trail). At an even more impressionable age, I saw that kill bee movie from the 70s (?) where they have to drive to the Superdome (?) and turn on the air conditioner to kill off the swarm. Except for the one bee left sunning itself high up on a seat near the roof where it was warmer. So I decided not to do the Tanque Verde trail. I ended up doing Pima, which was awesome. I like a trail that begins (and therefore ends) gently, to warm up and loosen up at the end. And cutting into the Catalinas from the west is great when you're starting at 6:18 am: you have shade nearly all the way up. The view from Pima Saddle is to die for.
Two inventions. The first is AI technology to stand on for a real person - I know, not really new - but the idea at first was to market it as a way to keep talking to a loved one after they've "passed." But then the idea evolved into having political/macro-social-engineering uses. The second invention was a backpacking cupcake restraining system. Where you poke tines into the cupcake, and have a cover on it, so the frosting doesn't get all mashed. Inspiration was daydreaming about rogaining with Isabel - to keep her going I'd have to feed her nearly constantly because she has little body fat - then I was thinking about what she likes to eat and could only think of cupcakes. Well, and Honey Nut Cheerios.
The day was colored by Annie Proulx because I picked up a book of her short stories at Logan. Colored = feelings of of despair and sadness and a stuckness on depraved acts. I expect I should be extracting some larger philosophical point about - I don't know - uncertainty in life, predestination, survival of the fittest, but maybe that comes later.
Found the depressions in the rock used/made by Indian women to grind mesquite (?), as per guidebook. Guidebook also described grass used to cut noses off Indian women accused of cheating on their husbands. Made me feel kind of Annie-Proulx. I mean, really, people should be able to do their thing in peace, and also, I hate it the double standard thing...
