"I wonder how tough it would be for the Border Patrol to follow them and empty the water tanks. It doesn't sound that tought to me." I was thinking about how a high powered rifle would do wonders for those water containers. If you think about trying it, make sure no illegals are anywhere NEAR those containers. You would be immediately arrested, sent to Mexico, and executed.
Then again, these "volunteer groups" might be a front for the Border Patrol who want to lure the illegals to a watering hole so they can round them up and herd them back to Methico.
We might need to get that word out to the Methican gubmint.(wink)
