I agree with Randy, Confluence is the place to go. Every person I have talked to there has always been real friendly and super knowledgeable. They are always willing to help us newbies out. Confluence Kayaks - Denver Kayak Instruction
If you find that their class schedule doesn't work for you or your son, also check with raguides.
