Do you live under a rock? Go look at what resorts consistently are pictured in Magazines, which ones get awarded for being the best, which one every pro lives at. Might shock you but Summit County as a whole is home to 3 of the best parks in the world.
No i dont live under a fucking rock. I justex started snowboarding this year so i dont know which resorts have good terrain parks. And ive never picked up a snowboarding magazine in my life.
