Organ Pipe is already a freeway for illegal entry. They get a lot of food and water help from sympathizers on this side. And because it is an “environmentally sensitive” area, vehicle traffic to curb their entry is also limited.
On foot, with a little food and water, it’s almost a wide open gate.
“They get a lot of food and water help from sympathizers on this side.”
So the question to ask is: Why aren’t people destroying those caches of food and water. No food. No water. No alien invaders.
