Good luck, Fred. Having failed to ever find anything in the Texas stores I've visited (Lubbock, Midland & Odessa), my personal theory is that it has something to do with the high concentration of Baptists (of which I am one) in the region. While lots of folks might been sneaking off to Las Vegas regularly during the early decades of legalized gambling, very few of them wanted to bring home any evidence of their sinning. Or, if they did, some family member later came across their vintage chips in a sock drawer and quickly flushed them down the toilet to protect their good name.

Hopefully, you'll have better luck in central Texas than I've had up here.
