That was the only one I knew of.
Ft Worth is the original. They opened one in McKinney that was busting at the seams with people until they started screwing people over.
I spent appx $2K a year there until I spent zero. Ammo, guns, military stuff (canteens, ammo pouches, etc) and survival type stuff. I bought my favorite and most expensive first aid kit ever there. Still use it.
