The Illinois Open Series is a series of disc golf tournaments in Northern Illinois. The series was started by players who wanted to run tournaments that they would want to play in. We don't believe in ripping off the Amatuers to pad the purse of other divisions.
After 2010, 2011 is going to be a little scaled back with only 5 events. We want to make sure each event is a quality event that players are going to want to participate in.
