We play Ultimate during lunch (12-1) on Tuesdays, Thursdays, and Fridays. All skill levels are welcome, even if you've never played before. The field is big enough to have a couple of games going, so the more the merrier.
I have added this game to meetup.com just to help new members find us. We do not use the RSVP system here at all. We always have enough players show up to play.
