How much a part does killingtons early closing have on the decisions of Mt. Snow particularly, and sunday river, sugaloaf and sugarbush to stay open late? I say Mt. Snow primarily because they are the ones who seem to be significantly adding to their season. Sugarbush closed on the same day last year as killington and i believe sugarloaf and sunday river have historically made it to late april if not may. someone correct me if i'm wrong.
