Start with Mohawk Mountain. It's a good start. The Hawk is winding down its 60th season - that's 1947, for you mathphobes - with Mohawk Madness on Saturday, a party to end all parties (or just to end the season) that runs from 9 a.m. until 1 p.m. Wear a costume, get a discounted lift ticket, compete for prizes knowing trivia or racing races. And Ski Sundown wouldn't be Ski Sundown with demo days. Sunday is Atomic Skis Demo Day all day.
