I was there about three weeks ago. I live in rockford and it was okay. Runs were longer than chestnut but not as nice as cascade. We went on a Friday night and they were packed. The blues were pretty nice. I'm too noob to do anything above that. The greens were so busy that they weren't very fun. I was not impressed with the snow either (all ice balls-I'm sure there is a term for it).
I'm hoping to check out devils head before the end of the season.
I'm stranded until after the storm since I drive a 350z lol.
