I was out there a couple weeks ago eating at the original. We left there and went to the new one across the street so my wife could make a sales call. I joked that they should have done a better job of making a fake old sign. It looks ok in the picture, but in person it looks like a manufactured old sign. I never understood why families have fall out's like this. My wife knows them well through her job so if anyone is interested in the story I can get it from her. She told me a while back, but I didn't care enough to remember. FWIW, it's not a new feud. This has been going on for a while.
I know enough to know what happened, but not enough to pass along stories that are sure to be factual. Bottom line for me (personally), I have known and liked Terry for a couple of decades. He is a good Longhorn. I have lived in town for a couple of decades and wouldn't know Kent if he walked in the room. That informs which brother I will buy meat from.
It would be hilarious of some unrelated guy named John Black moved in and opened up a bbq in Lockhart called "John Black's BBQ".
