I hated Park City when I was there....I guess that's because I don't really hit jumps but I would have to say Brighton. So much flow, I loved those tubes. Or Carinthia on the east.
I like Bridger because there's no " I'm better than you going around" and you feel like you can hit everything in the park confidently, but still try hard tricks. I like that
crotched mountain parrrrrrk. not really cause its a tiny ass mountain, but my favorite has gotta be carinthia, and sunapee wasnt as good but still alot of fun features
Although the features aren't immaculate like Breck's, I find Vail's park to be a lot of fun because there are never any crowds, and it has a high speed quad with no liftlines that takes you right to the top of the park.
