Valleyfair or Dorney the best park in North America? lol you've gotta get out more often, unless of course you like weak hyper coasters, good but not great B&Ms, and a severe lack of Intamin love
It depends on what you're looking for, but since I'm more interested in the coaster side of parks (though I weigh other factors too), I'm thinking Cedar Point, with honorable mention going to Great Adventure, and maybe Magic Mountain, Islands of Adventure, and Disney World...I don't particularly care for Disney World but there are millions of people who do so it should be up there on the list of the top parks too.
