Me: Hey, why don't you come out and ski in our tournament?
Non-tournament skier: Sounds fun, what do I need to do?
Me: Buy a USAWS membership for $85, pay the tournament entry fee, then go home and take a 90 minute course that has nothing to do with skiing. Then you'll be good to go!
Non-tournament skier: Nah, too much trouble. I'll just go the lake and ski with my friends.
Grow the sport!
