Colorado Athletic Club Boulder practices classic bait and switch. They tell you to buy a 12 month membership that will be cancelled if you move out of town and then when you move they either keep charging your card, saying there was no written notice, or send you to collections. I've spoken to a dozen people this has happened too and am setting up a wesbite: cacbisscam, but in the meantime post your experiences here.
BEWARE: BAIT & SWITCH.
