I went up there last Saturday and I was surprised that the conditions were much better than I expected. I rode from around 12:30 to 5:45 and it really didn't get icy until after dark.
They had the upper-right side open if you were looking at a trail map - Easy Out, Vista, Come Around Park, Upper and Lower Main St, Midway, and the Chute. They opened Lazy Mile up last Sunday too. The park had a few rails and jibs and 1 jump, I think maybe 8 features total.
They had Vista, Burma and Main St chairs open. If you feel comfortable on blacks then skip Vista, it was super slow and had a large line, and go on to down to Burma/Main St lift. There was a minimal line at the lower lifts and the mountain really was not very crowded at all.
