Considering cock fighting in a felony in NC, I didn't give the notion much of an idea.
The more I read up on it, can't help but think it's a 50/50 bet its on cock fighting.
That said, not certain I'd build a fence and put all that crap up in my front yard for everyone to see driving by the road if I was thinking about making money doing something illegal.
Although I'm not a choir boy by any means (particularly in my youth), can honestly say I never made money illegally.
Guess the difference between roosters and dogs is you don't have to train the roosters...
Guess the simplest way to find out if anything illegal going on is to follow the money trail (along with shipping), if you actually wanted to spend your time on it.
