You are just asking for trouble with this one. I have seen people turn out dogs on other people's property (my family's). They don't care which way the dogs push them.
Coosa County was one of the first counties put on the permit system. I am guessing well over 10 years ago. It was that bad there.
Now with that said. I am not saying that the dogs were trained on property lines and hunter directions. But, they were released on private property in which the dog hunters did not have permission to hunt. Trucks and CB's then took care of the rest back then. I guess it is cell phones now.
