Years -- many years -- ago, after a storm, the Caborca road between town and Mayan was one filled wash after another. It was around 9:00 PM and after successfully plowing through all that, we met worse conditions on the beach access road. It was pure slime -- mud that was deep and wet. Travelling on it was more like a "controlled slide," until -- on the downside of a hill -- we met our match. In front of us was a "graveyard" of a few jackknifed, semi-buried vehicles. With that, we revved the tires (mud flying) in reverse, turned around, "slid" our way back out, and began our 4-hour drive back to the States. At the border our vehicle was totally encased in thick, semi-dried mud, except for some wiped-away portals on the windows. After sharing our story with the border officers, they merely laughed and directed us onward. All that to say, I'm thinking the too-much-mud accuser was just fun'n with you.
