Been to many missions in cal
From some of the comments may hit Daley plaza and stop awhile in austin
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.
In 1966, I walked over to Dealey Plaza from the downtown hotel where I was staying. At the time, it was merely a park and an intersection. The famous school book warehouse nearby was probably still being used to store books. I saw nothing to indicate the area’s historic significance.
