When we began driving south, always using Los Mochis as a stopping point, we understood there to be two RV parks but one was said to have closed without us ever finding it; the one we visited two or three times had the chickens nearby and had a tricky exit if going south. But the last time we visited, possibly in 2004, there was nearly a foot of water covering the entire lot, with water still bubbling up into the lot. Lots of rigs were still there, owners off perhaps on the rail trip to Creel. It looked like some would be taking on water, and we got out of there as fast as we could, never to return.
As RV travel really tapered off after 2008, we stopped at La Pilarica. Trucks were everywhere, it was jammed packed. But not one other RV; there had always been others there in the past. Next to us in a sleeper semi, things were getting rowdy. We opted not to leave our rig for our usual visit to the cafe, and as darkness fell it got noisier next to us. This was too much, and despite never driving at night, we pulled out and drove to the next Pemex down the road, for a quiet sleep. One of only two times in 20,000 miles driving in Mexico when we drove at night, when we felt vulnerable and uncomfortable. The other when stopped over night, heading towards the Texas border at Piedro Negras. Yes, that was another Pemex.
