If you're afraid of making a "fool" of yourself by probably not being as good of a skier as than someone else, don't be. There are always people who make fun of less talented or less experienced people in every sport, but I would imagine COC to be a place where there is a minimum amount of that kind.. This isn't a team sport, so you don't have to care what others think about your abilities, and besides, you're there to improve yourself and have fun!
Those who make fun of others are, in the end, ignored by others. Don't care about them.
