Chicago has one of the largest gay volleyball communities in the United States, with 3 gay sports associations running leagues year-round.
I tried looking under NAGVA- north american volleyball association to see if their were leagues posted for Chicago - unfortunately not. I typed in Gay Volleyball Chicago under google. Mostly what I found were old sites for the Gay Games. The clip I took up above is from one of the sites.
Good luck. I moved out to Vancouver a few years ago and was actually picked up off the street and asked if I wanted to play. I was looking for a league for at least a year prior to that. It's alot of fun and the tournaments are fun. People from all over have kept their friendships with other teams from across Canada and the US.
