all are gonna be crowded, vail usually has the shortest lines if you know where to go though. breck, probably most crowded, a-basin, the base line is always long as hell but up on the mountain its not as bad. keystone, go to the outback early in the morning, then work your way back forward, that kinda avoids lines. or, just reserve a day at silverton for next year. thats not crowded at all
