Keystone has the best park in Summit County bar none. Breck gets a lot of hype but seldom do Snowboarder Magazine or other mags represent what a great park Area 51 has become. If you want tons of features ranging from beginner to expert this is you mountain. Plus you get to ride at night which brings endless amounts of fun and jibbulation. If your tired of riding park take a cruise to the Outback with hidden runs in the Windows and the bowls. Overall Keystone has made me and a lot of my friends into better more well rounded riders from park to trees to powder.
