Up in Aroostook County, Maine, winter arrives early and stays late. It's good to have something to do here in the state's largest county (larger than the rest of New England combined, in fact) and despite the popularity of snowmobiling here - almost everyone's second car is a snowmobile - it's best to have another choice. The sport of alpine skiing is certainly not unknown here; Big Rock was established in 1960. But it declined in popularity over the years as prices rose, making it more difficult for families to enjoy a day's outing. In a bid to change that the Maine Winter Sports Center (MWSC), through grants made available by the Portland-based Libra Foundation, purchased Big Rock in 2000 and has made steady improvements to it since.
