I did it last weekend at bromley multiple times on different trails when there was 8-10" of fresh powder. It was soooo worth it. I only got caught once, and the ski patroller simply asked me what I was doing on closed trails (pretty obvious answer), why I shouldn't be there, and then let me go. He didn't clip my ticket or anything, even though it was only a single day ticket anyways. Out of the 4 closed trails I went down, 3 opened the next day anywyas.
