Just mine the damned border and be done with it.
I was going to say "you must be new," but you're not, so you must have just missed it a ways back... There were some threads about securing the borders, and other threads about how alligators in FL have lost their fear of humans, and there had been a spate of attacks. Well, this being FR, someone came up with a way to fix both problems at once... Build a moat along the border, and stock it with alligators, especially the ones who aren't afraid of people.

This problem is way beyond fixing now...All that is left are consequences.
