I travel a lot for a living. All over the US. On my travels I spent some time in Texas and drove through La Grange a few times. It's a nice town. Pretty ordinary middle US rural farm town. You can look up pictures online. The thing is there is only like two or maybe three main highways that lead into La Grange and I've driven down all of them. There is no bar/whorehouse and nothing very much like a shack at all. In fact this picture of a small unused building is the only thing I found that was even remotely "shack like". Sorry to burst your bubble but despite the ZZ Top song, There is no, "Shack outside La Grange". Just pretty ordinary farms and hard working people.
