Climbing and programming go really well together. In my most productive periods, I get into this cycle where I climb a mountain right at my limit, scare myself just the right amount, and think to myself, "Man, I don't ever want to climb a mountain again." Then I go home and work on fun technical stuff right at my current limits. I work at that for a while, until I want nothing more to do with computers, and just want to be outside. Then I head off into the mountains. It's a good cycle. :)
