Not Saddlesore, but while ski lift tickets are not marketed at out of state and instate rates, some of it does exist in practice. Most (all?) of the major Colorado mountains offer season passes and other lift ticket packages at reduced pricing. To take advantage of may of these offers, you have to come to a Colorado-based location to have your photo taken for the pass and to register. I suspect a frequent flyer could figure out how to get it done without living in the state, but for a family that does not live in Colorado, it would probably be hard to accomplish.
As an example, Copper Mountain offers a "Four Pass", meaning four days of skiing for about $140, if purchased well before the beginning of the season (now). A family flying in to ski for a long weekend would probably pay over $100 per day per person for lift passes at Copper.
