I'd like to invite you to southern Arizona for a look at what Monte is talking about .
Arizona State Police and California Highway Patrol, 'unofficially' tell people not to drive on Interstate 8 which runs between Casa Grande, Arizona, which is about 45 miles from downtown Phoenix, to San Diego, California, which is about 350 miles in distance, at night, due to the illegal drug and illegal alien smuggling operations that go on daily .
One exit that I used to get off of, led to an area where you could watch live ordinance runs of F-16's, F-18's and A-10 military aircraft at the Barry Goldwater Gunnery Range .
As soon as the pavement ends, there is a sign that states : 'WARNING : This area is a known corridor for illegal drug and alien smuggling . Avoid any contact with other people . Enter at your own risk .
This part of the Sonoran Desert Monument, a national park .
I bet if a sign like this went up at a park 41 miles from Washington, D.C., there would be outrage like you've never seen before !!!!!!!!!!!
As the 'crow flies', this about 41 miles from downtown Phoenix .
