Since there is not much going down in the frozen tundra we call Montana this time of year, here is a cool link for you to check out.
spotcovr.com. It is a site that uses google maps to document skate spots around the world. User submit content and rate each spot, add photos, etc. You can even get driving directions. It seems to be pretty new yet but it might be worth checking out in about a year on your next trip to find some good skate spots outside of Skatepark directories.
