You didn’t say you were coming from California. There are missions in New Mexico and probably Arizona. If you are driving from California, Fredricksburg is an interesting old market town, shops and art galleries. There are small old Sunday houses where families stayed when they came into town for Saturday shopping and Sunday church. Some of them are now bed and breakfast places. Fort Worth Stockyards area has stuff going on. You can ride a longhorn steer and have your picture taken on it if you are able.
Flying in
I have wires in my chest. I’ll eat some steer, but no rides. Lol
+1 for Fredericksburg, home of Admiral Nimitz & the WWII Pacific Museum. You won’t have time to see everything, so make sure you do the Combat Zone - it’s the guided tour portion & you’ll see a plane like Bush 41 flew, a PT boat like JFK’s, American & Japanese tanks & a field hospital.
