I've been playing Ultimate frisbee with some co-workers at lunch lately. (Ultimate is a lot like soccer with a frisbee.) It's a great game, although our field tends to be very muddy most of the time so we tend to get pretty messy! I'm new to the game but learning fast, I thought I'd post a couple good resources that I found. www.ultimatehandbook.com has some good information, and this pdf document my co-worker sent me is really good for explaining the game for beginners! I've been mixing indoor soccer with ultimate, my shins are taking a beating right now. Hopefully after I do this for a few weeks in a row it won't hurt so much!
