Yes, there is a Wednesday night league there. I'm going tomorrow night to talk to a guy from the park district that also plays there. Right now it's register by 5:45, tee at 6, $6 + $1 optional ace fund.
See you guys there if you go :)
They also are having a tournament for $10 single round it looks like at their grand opening on Sat, August 20th. You get a disc for the entry fee, expect it to probably be trophy only. Adv, Int, and Nov. Make sure to play up out of novice to let true beginners have a chance to duke it out ;)http://www.genevaparks.org/facilities/links_disc_golf.html
