Why not fence in about a two mile wide swath along the border, and create a 2,000 mile long wild animal sanctuary with bougainvillea planted all along the fence row? Populate the sanctuary with hundreds of mountain lions, timber wolves, grey wolves, coyotes, herds of bison, elk, moose, black bears, brown bears, grizzly bears, rattlesnake pits, copperhead areas, coral snakes, cotton mouths, pythons, anacondas, alligator ponds, Yellow Jacket and Hornet hives, Black Widow spiders, Brown Recluse spiders, Scorpions, and wild boar.

We could provide sanctuary for endangered, threatened, or vulnerable species, while securing the border for a fraction of the cost of constructing a wall, and cheaper than mowing the grass. I think people would be willing to pay a price to go through an F.D.A. feed supply station and feed the animals, under the supervision of U.S. Border Patrol, of course. This could become a new source of revenue. Want to climb over that fence? No way Jose!
