I don't know man, bringing a girl to mammoth does wierd things to their brains. They instantly become full of themselfs because if they are even *semi* hot They look like a godess to all the horny skiers and snowboarders. (girls are in extreme short suply, therefore ugly chicks get away with being total bitches. I'm not saying your chick is ugly infact there is a good possibility that she isn't ugly at all. Thats even worse though, you see, she will meet some pro snowboarder fall in love and never talk to you again)
all hypothetical of course, but when it comes down to it, there are no girls in Mammoth, and the few that are there are in total control.
Unless your girlfriend is cool... then its a different story.
