I can't say enough GOOD stuff about joining a ski club.
What to look for? Depends on your own needs.
For me - I wanted the discounted lift tickets, the lodge at the base of a mountain so I had cheap digs. People of my own age group to ski with.
What I got? A GREAT group of people who are quickly becoming a second family. Free lessons all of last year that brought my boyfriend from a solid Blue trail guy to a double diamond skier. Kids for my own son to ski with. A lodge at the base of MRG that allows us to roll out of bed, eat breakfast cooked by a hired cook, slap on our ski's and ski down to the lifts. Vermont in the summer for $10 a night, club sponsered ASIA training, off season events like rafting, hiking, kayaking, mountain biking.
The best part? I'm not looked at like a complete crazy woman because I'm surrounded by other ski addicts!
