i wish my hill was longer D: i live in MN so i have no mountains. bummer. the runs are like a couple minutes if you flat out bomb. the ride up takes like 5 minutes with a decently fast chair if that gives you kind of an idea.
I feel you, that's kinda what I'm going through with these CO hills so far.
You gotta get up to Alyeska in Alaska and hike way off to the right @ the top of chair 6. Then you can mash and the run will still take you 20 minutes!
