We plotted a route up the East Coast that would take us through SC, NC, VA, DE, MD, NJ, and NY. Our map, photos and comments are on our web page at http://www.snowbirdrvtrails.com/bluedot.htm.
We have also done a swing through the New England States and posted it at http://www.snowbirdrvtrails.com/orangedot.htm.
There are so many route options and things to see and do. You have received some great ideas already from your post. Planning is a big part of the fun we think. Whatever path you choose you'll have a blast! Safe travels, Jack & Niki
