Been going on for a LONG time now. Back in 2009, we had some moose hunters from Texas. One was telling me of the problem with hogs then. I mentioned that I wish we had them, and he said: "Daryl, no you don't. Once they get established, they over populate and cannot be controlled. We even have feeders for them, then the lights come on and we shoot and shoot and shoot. There is no controlling them. The breed too often for that."
