There are a couple other threads about that route, but some are from Houston to Dallas. Same difference.
Now I realize that the same places are mentioned in all of the threads, and the chowhounds are split down the middle on the BBQ at Woody's. I cheated last time we went and had a deli sandwich made (corned beef on rye.) My husband had a chopped beef and it was pretty good. I was salivating over this smoked chicken that the woman sitting next to me had. She ate a half a chicken in one sitting, and she was a little thing, so it must have been good. If they have the german sausage on the steam table, order that. One of the guys there makes it himself.
Good luck and hope these help.
