My Grandpa used to claim it was cause the "colored's" spend all their cash on Cadillacs, Marijuana, Booze, and loose wimmen...........
Then he was likely kinda racist. Ran a small bar in the Ozarks.... wink, wink
A couple generations later I can clearly see that it ain't the Blacks buying all the cadillacs, smoke, booze, and enjoying loose wimmen.
Lots of old (and some young 'uns) dogs dig that ****, too!
