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.
While there are only three confirmed events so far for 2012, there are a couple more in the works. Details will be posted here when these events are confirmed.
