Chadds Peak perhaps?
I used to ski there every day after school in the 80s on my high school ski team. Great memories of friends, poma lifts, night skiing, and slalom racing. Every time I ski at night I think about those care free nights spent at Chadds Peak.
Here is a link to the DCski website where they have a couple of pictures of the place nowadays.
