Any reasonably ski-able one I have all to myself, or just share with just a couple of buddies.
As for the coolest run imaginable??
How about something above the tree line being a varying 30-40 degree pitch but actually having some trees for ambiance (yep, something above the tree line with snow that light and air that thin, but with some arbor scenery magically there). Powder bowl for about 2500 vertical feet, transition to nice natural bumps/moguls for about 1000 vertical feet, then a rut free corduroy GS course for the last 1500 vertical feet, ending at a picnic table complete with piping hot chili cheese fries and an ice cold mountain dew.
Oh, and my skis would magically change from 100 underfoot 190s to around 67mm 180s when I hit the bumps, then get longer again when I hit the cord..
