Hi Pam!
It was good to meet you while I was in Clarksville, TN 2 weeks ago! I am glad to see that you are using the forums as a resource for your trip!
Don't forget Cape May- it is the southernmost tip of New Jersey. You could start from there and work your way up the coast- fortunately, New Jersey isn't that big! (no offense to our friends in NJ).
Have a great trip- I wish that I were with you!
