Mountain sled - there is powder in the trees and on the north facing slopes, enough to carve and do turns, we did have a good time - but if you are looking for 1.5-2 feet of untouched snow I don't think you will find it on Monday unless a storm rolls through.
As for driving 12 hours - that's up to you. It was a bluebird day in the morning, so we did some exploring and had a blast. The clouds rolled in around noon but no snow, hopefully the 40% chance today will come through with some snow.
