Don, there's another solution to animal overpopulation.

We can reinstate the predators. Mountain lions (a/k/a panthers, painter, catamounts, pumas, etc.), both types of bears, wolves (the coyotes are already back). Let them copulate and populate and eventually we'll restore the balance that was there before we messed with it.

Of course, this solution brings a few problems of its own with it, but heck, it'll cut down on the number of joggers!
