Bet nobody can top this! Afton Alps, outside of St. Paul, MN. 350 feet of vertical! My people are from the Twin Cities, and 30ish years ago, my brother and I took our skis out during our holiday visit and skied Afton Alps with my cousin.
Other than that, GP, Song, Toggenburg, Stratton, Gore and Killington (1987) where I had a major wipe out on the mogul trail that the bar looks out on and bounced my way to the bottom. The bartender who kindly gave me ice for my knee, as well as my beer, said they watched me all the way to the bottom.
And, of course, various cross-country treks, mostly bush whacking.
