(I may be going in on a vacation house near Deep Creek Lake and was curious what the other ski options would be in the area besides Wisp. Seven Springs also seems relatively close.)
The other major attraction on the road is the Wal-Mart in Oakland. I suspect what JohnL wants to do is hit Wisp in the morning and then do T-line in the afternoon and evening. I think that is an entirely doable Mid-Atlantic ski safari.
