When we cleared out lot up there we took and transplanted them all around the outside perimeter of our fence around the property. No one thought about testing the fence, could not even get through the cholla to get to the fence. lol
I picked a bunch of them off the backside of a co-worker once. He got out of the dump truck and all I heard was Son OF A B***H!
His wife worked on the festering pimples on his backside for weeks after that one.
LOL!
