Perry’s right.... There are some areas like the Rio Grande valley where a fence is not practical. They’ve put up a wall in areas that cut ranches in half. There are Texans that actually live on the “mexico” side of the wall. Cutting Americans off from a major natural resource is...”ridiculus”. There are alternatives.
Thank you for posting that information. I’ve read this before but wasn’t sure if I would state it correctly. Another poster already mentioned the problem with terrain and geography.
