Hey. My brother and I are planning a road trip from Monterrey, MX to NY and are looking for suggestions.

We have a tentative itinerary planned with the only firm date being August 6th in Memphis.

30-Leave Monterrey
pass through Austin
Arrive in New Orleans approx the 31st or 1st.
6-Be in Memphis by today
Then to
Nashville
Savannah
Asheville
Charlotte
Richmond
DC
NY by the 16th

If you have any suggestions of what to see/eat/avoid/add/delete, if you know of any festival (music, art, food) close to any of these cities between these dates, and fun "road tripy" must sees, really anything would be really appreciated. Especially suggestions for the long drives we have planned between Austin to New Orleans and Nashville to Savannah would be welcomed.

Thanks.
