This map, designed by MIT music professor Michael Scott Cuthbert and researched by writer/designer Nate Barksdale, can help you plan your trip. The United States is organized by volume above sea level: the more high-reaching areas a state has, the more space on the map it gets. So the mountainous Southwest ends up holding on to a lot of its space, while the relatively low-lying South has almost completely vanished. If you're into cooler climes, Alaska seems to be doing pretty well, too. Rhode Island doesn't have much space left at all--but maybe if there's a tiny bit post-apocalypse you can create a Waterworld-style fortress island.
