People may not understand how important this is. Border Patrol has been kept out of most of that zone by previous administration’s National Parks Service. They were concerned about federal agents distributing the ecosystem. They were completely unconcerned about the illegal entry on non citizens and the havoc they caused the ecosystem with the foot traffic and garbage left behind. This is where all the drug, gun and human trafficking occurs. In between the ports of entry.

I suggested making our borders into Military Bases many years ago, knowing that farmers and ranchers along the borders (any property owners) would be happy to accept fair market value imminent domain settlements to sleep soundly at night, knowing the Military would close the borders down and keep them closed.
It's finally happening.

Try crossing this, and grounds all loaded with sensors!
