Trek in Calgary will accomodate him with the waiver I believe. It's just the teams around the area are all 18+ period and to be honest I particularly like it that way. Other venues are free to set their own rules and regs but I know what I like and will continue playing with the group that I play with.
@OP: I suggest you wait and hold your horses. Bide your time, there's tons of other things you could be doing. Restoring a bike (CB250's and the like are the cool things to be doing restoration projects on these days), chasing tail, brewing your own "beverages", MX or XC biking, smashing rocks, detonic chemistry (fuck yeah!).
