If I was a rancher on the border I might just do that. I think I'd set up a water station in the shade whereby you push a button, and then have to wait 10 or 15 minutes for the water to come out. In the meantime, a signal would be automatically sent out to the Border Patrol.
Well maybe they will file suit against them using the latest Supreme Court decision to seize the ranches IN THE INTEREST OF PROMOTING THE PUBLIC GOOD. They can use the ranches as waystations for the illegals, terrorists included. A Document center (fake ofcourse), maps to the illegals chosen city. and heck lets go for the whole enchilada, transportation to said city. And ofcourse the INS,HLS,FBI,etc are forbidden from entering said property.
Don't forget medical services.
