Yep, Cupp Run and Shay's Revenge at Snowshoe has the most single run vertical in the Mid-Atlantic, approx. 1,500 vert. ft.
Other verticals of approx. 1000 ft. vertical include Highlands area at Wintergreen, most top-bottom slopes at Timberline, top to bottom at Whitetail, Paradice from top to bottom of lodge slope at Massanutten, top to bottom at SNO Mountain in PA, and at least one run at Sugar in NC, maybe a couple of slopes at Elk.
Anyone think of any others?
