I finally got to watch a couple games of an Ultimate tournament today, since I'm in Reston VA on business, and Alex's team happened to be in a tournament here. It took me a little time to figure out the rules, but after a while I could tell when a point was scored and when good plays were made. It was a gorgeous (though windy) Fall day, lots of fun.
I tried to catch some of the action, but I mostly ended up getting the shot right after the disc was thrown – it's a very quick game!
