In the heart of Big Sky Country you will find the 14,000 acre Yellowstone Club, an elite ski and golf resort that counts Bill Gates and Bill Frist as members. There are only 250 members of the Yellowstone Club, and once you hear the dues breakdown, it's easy to see why. It costs $250,000 just to join, but you can only become a member if you have a home in the vicinity (which would cost you between $5 and $35 million). Annual dues are $20,000. If that isn't enough for you, you can upgrade your membership to "worldwide" status for a mere $2 million in order to gain access to other Yellowstone properties around the world. Yes, in case you were wondering, the skiing is supposed to be pretty good.
