i only ski the small park anyways (well, i ski all over the mountain, but if im doing park, i just go for the small one), so i really dont mind. as to why, no idea.
The only thing keeping big sky back from having a dank ass park is a lazy park crew. Also park isn't their first priority, but if we e-mail them and make sure they know we want a big park early in the season it might help.
