I can guarantee you those owning property on the border are all too well aware of the problem (including deliberate trashing of their personal property) and getting ignored by their elected representatives!!!!!
Hiking along the Santa Cruz near the border - I came across 30+ illegals underneath an overpass - needless to say it was an awkward situation. I left and called the border patrol and they said they couldnt respond. Come to find out that this spot is used all the time to transfer illegals and the border patrol knows about it but does nothing to catch the illegals who hang out there. GW is 100% to blame for all of this - he has the power and the influence to change this but cares more about business then the security and welfare of American citizens.
