In response to some recent conversations, here are a few tips on touring the East Coast USA:
The East Coast is the basis of much American culture, it's a good place to ride, and flat and easy. It's heavily developed, if you want more scenery I'd recommend detouring inland to see the Appalachian mountains, especially the Great Smokey Mountains. Try lots of food, music, etc., and meet people. In the Southeast, I'd recommend seeing Miami, Key West if it's not too far out of your way, Savannah GA, Charleston SC, and lots of small towns. In the Northeast, the major cities are all tied together, I'd ride all of those. Baltimore is a surprisingly good city to visit BTW. If you can, try to make it to New England (MA/CT/NH/VT/etc.), at least for a bit, it's one of the nicest parts of the country. The people in the Southeast (not including Miami) tend to be friendly, warm, although conservative. The people in the Northeast cities tend to be more sharp, liberal, although sometimes quite rude. Overall it's a great trip and I'm sure you'll have a good time. Please let me know if you want anything else! :)
Rock & Roll!!! :)
Update with further thoughts:
In Florida, aside from Miami and the Keys (popular places to visit), the Everglades are gorgeous and have an ecosystem unlike anything else in the country. Georgia is one of my favorite states, it's very rural, the people incredibly friendly, and everything so beautiful. The Carolinas and Virginia are very historical, worthwhile especially for those interested in early American times. In New England, I would highly recommend the seacoast, it's charming and a lot more interesting than the interior. The people there are friendlier than the rest of the northeastern states, and the food is delicious.
Going inland, it depends how far you go. If you're not committed to staying close to the coast, you could venture out as far as Louisiana, which features New Orleans, Cajun country, Creoles, and more. To get there is a long way through Alabama and Mississippi, which have their Deep South charms although are quite culturally different than much of the more modern states. Tennessee and Kentucky are some of the most scenic states, which I think you'd like. They have hills, farms, towns, big skies, good music, and horses and whiskey. Very American.
West Virginia is a nice camping area, it's got a small population. Pennsylvania is a diverse state, blending together tastes of many neighboring states. Up north, if you venture further inland, Chicago is worth a visit. Indianapolis is surprisingly cosmopolitan, and southern Indiana surprisingly scenic.
Texas is a neighboring country, which if you feel like could provide a different view of the US. :)
