I live in the Boulder area and I'm looking for roll classes. BOC/RAguides offer classes for $50. Since I'm new to kayaking and I've heard that to get good enough to effectively practice rolling on your own, it may take a couple classes. I did a roll class at the Silverthorne Rec center for $25 last year and that kind of more like the price I was thinking about. Since dollars are an issue right now, does anyone in the greater Boulder area know of a cheaper place to get some instruction or am I stuck with $50 a session?
