yean man, one time i was at camelback, PA and i was casually carvind down a totally empty run switch, and i was perfectly under control and stuff, just enjoying myself, and this ski patroller stops me, he pulled up to the side of me like some friggin cop, and blew a whistle and waved me down and shit, so at this point i was laughing, "i was like so officer was i speeding, did i run i stop sign?" haha, so he pulls me over to the side of the trail with his really annoying whistle and custom red fleece wiht red deflectors, and was like "son, what in the name of whatever are you trying to do here? skiing backwards? you could easily run over someone, you dont see, or take a out a family having a grand ol time, so im gonna have to ask you to ski normally, an never pull a stunt maneveaur like this again" and i was like, but um sir i was lookingover my shoulder, so i had full visiblity, i had perfect control of what i was doing and ther eis nobody else on the trail that could interfere wiht me, then he was like dont back talk me, ill take away your pass or report you to the other patrollers or w/e, anyway he eventually got another radio call and just told me to ski down like a normal human not some trickster punk haha, i just started back up switch again, but at this point he just didnt care, caus ehe had his other call or w/e so yeah i dont see what the problem is but, i mean if you have control of your skiing, and your not doing anythig stupid then let me ski switch haha, as for alta, well idk just do it anyway haha
