I'd have to say The Catskills (with more than 30 peaks above 3,500 feet), The Adirondacks (and the 2.3 million acres of State Park), a certain U.S. route that goes over Mt. Monterey, (et al), Lake George, driving down the Hudson Valley to New York City and seeing the layers of billions of years of sediment, looking out at the ocean when you're in the middle of the Chesapeake Bay Bridge-Tunnel, accessiblity, diversity, and complexity.
