Team Colorado Whitewater Racing is doing a summer program for kayaking, and we're usually around the Boulder/Denver/Golden areas. We mainly are a competitive slalom club but also do beginner whitewater lessons. There's two weeks left in the summer program with some real kick-ass ACA certified coaches, with programs going into fall and winter and pretty much all throughout the year. We can supply you with boats and gear and the best part? It's only $80 a week, five days a week, 4 hours a day of supervised high performance training. The program can be found here:
