I am trying to plan a southern US roadtrip this summer and am having a bit of a problem trying to occupy 2 weeks with lots of things to see and do. My Initial plan was to fly into Nashville and stay for a couple of days, then onto Memphis and stay for a couple of days as well. Then south into either Mississippi or Alabama and then onto to New Orleans ending in South Padre Island or another nice beach town in Texas. We enjoy amusement parks, historical sites, plantations, beaches, music, food....pretty much anything and everything. I've been to New Orleans once before and loved it and really want to show our 13 year old son the French Quarter, etc...anyone with any tips or suggestions?
