Interestingly, the states just mentioned are the only ones I have yet to add to "my map." They would be Mass, Conn, RI, Del, and New Jersey.
I've been looking at a map thinking about how to travel in an RV from one of these states to the other. It is certainly more complicated than traveling from East Texas to Geogia (for example.)
For me it is complicated by the fact that I try every way I can to avoid the large metrapolitan areas.
Anyway, I'm just thinking about it, not planning for it just now.
EDIT to say: I'm speaking of the 48 contiguous states. We have not been to Alaska in our RV, nor to Hawaii, though we have enjoyed visiting both. We have never been south of the border, and only into Ontario with our RV.
