Thank you Northloper, I had read earlier from another post about an issue. The Rv'er tried to get back into the bus lane from the auto lane, but did it too late. Much damage. The Rv'er explained about lack of road information. Please understand whether or not true, I wanted to check it out. It has been 5 yeas since traveling back and forth into Mexico thru Nogales. And yes I know all about Lukeville, San Luis and other border crossings.
