Correction, mountain creek owns the helicopter and it stays there full time to heli people out. The urgent care at the bottom of the mountain is staffed full time when the mountain is open, and not by ski patrol (there is a separate group of employees/nurses that are there).
It's actually absurd how much the helicopter gets used, at least a few times every weekend. The presence of not only NYC dipshits but also the asian gapers that get driven in by the coach bus usually amounts in a shitload of injuries all the time. Last time I was there I saw a girl that completely blew out her knee (gaper coming off a knuckle and landing wrong), a boarder who broke ribs knuckling a really steep tranny and got knocked out, and some asian woman who skiied past the hill you stop at and into the lodge (idk what resulted but it looked bad).
