If you are in college, mount snow. Illest parks around and the higher education pass is $275 for 4 mountains(Mount Snow, Big Boulder, Attitash, and Crotched). Its well worth driving a bunch more to ride a park with a variety of features that are actually set up well.
If not in college, I would go with butternut. Back when I was in high school it was 250 for the season and depending where you live its only a 1-2 hour drive.
If you're talking local then obviously sundown, but thats like 500 bucks and imo i would rather drive further for a park that has real jumps.
