Being from Jersey, there's a certain amount of pride I take in that fact. Although I can't really articulate why beyond my home town's (Jersey City) tough guy rep. The Pine Barrens might pick it up a bit, but I've never been there, sorry to say. Our beaches are also quite nice; you can see dolphins jump from your outdoor restaurant table in Cape May, for instance. Bottom half, for sure, but maybe in the high 30's.
Alaska should be in the top 10. Calving glaciers, bears, moose, orcas, and where else can you see rain forests and glaciers/tundra in the same state? Anchorage is also one of the coolest cities I've ever visited.
Arizona's got the Grand Canyon. Easily in the top 15. South Carolina, for all its faults, also has Charleston. Hot as balls in the summer, but a nice city to visit. Ignorant rednecks and a shitty economy do drag it down, though. Top half, maybe? I mean, it's GOTTA be better than West Virginia, North Carolina or Kentucky, or Iowa or some such dull midwestern red state.
And anyone who says Hawaii doesn't belong in the top 10 has probably never been there. I was on 3 islands (Oahu, but only for a day, maui and Kauai), and can't wait to see the rest. I hear tell you can hike thru an extinct lava tunnel at night to watch the erupting volcanos. As a hiking enthusiast, that's gotta be one of the most unique hiking experiences possible, and next time I'm there, I'm definitely doing that. That's GOTTA put it well into the top 10.
