While looking for something else recently, I came across a story about Lake Wort near Fort Worth, Texas that contains several references to illegal club names and people who operated them near Lake Worth Casino, an amusement park in Tarrant County. This might have some names or club history that can be pieced together with other research ongoing on illegals in Texas. Hope this helps.
