Welcome to the ridiculously diverse United States, more than 3.6 million square miles chock-a-block with spots where you can follow your bliss. For some that means scouting out gators in Florida's Everglades. For others it's paddling in Lake Superior, the world's largest freshwater lake. Or hiking through New Hampshire's White Mountains along a prime stretch of the 2,000-mile Appalachian Trail. Or visiting the cliffside dwelings of an ancient tribe. Whatever it is, it's a safe bet you can find it here.
