I like the route TJ takes...following the food and drink. LOL
Las Cruces, NM
Kerrville, TX (be sure to visit Fredericksburg - interesting history) : Take Elli for a walk at Louise Hays Park. You can also take her to the The Coming King Sculpture Prayer Garden which is a nice place to visit. Grape Juice is a must for tapas and great wine. They also have craft beer. In Fredericksburg, go to the Pioneer Museum Complex (don't miss the short film), if you want to get your pulse up climb the Enchanted Rock (it's great), The National Museum of the Pacific War is on my "to do" list. Hopefully, I'll go there as I head to AZ next week from NC.
I avoid San Antonio now and prefer to get to the hill country, but I did go there and did all the things: the Alamo, Riverwalk, Missions. If you do go and if you stay at the KOA, be forewarned about the burrs. It was an ordeal walking the dogs there and the 20 minutes afterwards getting the burrs out of their paws and body.
Breaux Bridge, LA (do a swamp tour). I used Champagne Swamp Tour (I admit I thought I was going to get a glass of champagne on the tour and that's why I booked with them ?. No champagne, but the tour was great. Who doesn't like to be on the water with huge magnificent trees and huge rat looking animals. The gators were hibernating when I went so I didn't see any. What an incredible ecosystem....so clean and the trees repel mosquitoes.
Orange Beach, AL or Foley, AL (so much to eat and do. If you go there I spent 5 weeks there and can give you a list of restaurants and things to do, places to see. And of course you have to have the obligatory Bushwhacker.
Tallahassee, FL (overnight at HH at the Automobile Museum which is amazing)
and go up coast and visit Savannah or If want a more direct path, skip Tallahassee and go through Auburn which surprisingly has a wooded CG that is right off the highway with pull throughs along the river.
