Second up would be bike riding. Some of you might have seen my bike pics here or there over at ca.com. I mean real actual, pedal it with your own two feet bike riding. Its fun, I love it, and get no where near enough time for it. Hopefully this will change with the new job I'll be starting soon.
Uhm....light gaming I guess ranks at third. Used to play World of Warcraft, pretty much dropped thet. I use my ps2/xbox/ds more than anything now.
Working on my car. Its old and crusty, so it needs lotsa this.
Browsing the web, I'm a sucker for teh intarnetz!
