We will be driving from Houston to San Antonio on Wednesday to visit friends. We've heard we need to stop in Luling and go to Buc-ee's. Any other suggestions of things to do or see? A place for lunch? We will be staying in San Antonio for 4 days, and our friends will be showing us around, so we aren't in a hurry to get there. We're coming from Indiana, and my husband and son have never been to TX. So really we are up for anything. It can be obscure (I saw something about the world's largest pecan?), or maybe some beautiful TX scenery? Any historical sights? Thanks!
