If you are interested in playing Ultimate Frisbee:
There is pick-up on Wednesdays 6-8pm and Sundays 3-6pm. We play at Arrigo Park on Loomis St. between W. Harrison and Taylor. New players are welcome! We play year round, even through the winter! It is not competitive -- just a good time.
Also, check out Ultimate Chicago. http://www.ultimatechicago.org/uc/index.php. This is an organized league and the play is more competitive. You can play in the fall, spring, and summer seasons. On this website there is information about other pick-up groups around the city.
I play pick-up and league. It is awesome! If you want more information, send me an e-mail katherine_garlo@rush.edu.
