I've found that climbing is just about the most fun you can have with your pants on. I've done all kinds of sports in my life, but this one is definitely "it" for me. There's something very Zen-like about climbing, and even though it's technically a solo sport I like the social aspect of it.
I'm a programmer by profession, but I like to think I don't fit the stereotype. Well, not the standard programmer stereotype in any case.
To paraphrase the Sirius Cybernetics Corporation, "I'm your plastic pal who's fun to be with."
