I am sure is is not legal. I don't want to be the bad guy and turn him in. But I do feel he should have to have what I was required to have to be legal. In other words I could sell barbecue much cheaper with a cooker and pop up than I can with a certified trailer, business license, insurance, gov fees etc.
It would be like a NASCAR Race and one driver getting a 30 lap head start. I don't mind it he does good so long as he does not have an unfair advantage. I am inclined to let him hang himself and stay out of it but I just wondered how others handle it.
