I hate to say it, buit I think we are delaying the inevitable. We might as well toss them into Lake Michigan right now and get it over with. I don't know how they get around dams, but they do.
Maybe it will be ducks transporting eggs on their feet or some a**hole chucking a few into the lake 'for kicks' but they will make it. The barbarians are at the door...
