Looks like a great trip so far. As far as the east coast there are some amazing sites to see the whole way down.

Look into;
Nags Head
St Augustine (on of my favorite east coast stops)
Virginia Beach
The Appalachian Trail
South of the Border between NC and SC is always a fun little tourist stop if its your first time through.
Fountain of Youth


Good luck I hope to see more of your pictures when you are done with the trip
