I think that was my point. You can park just about anywhere. Of course, common sense comes into play. The Parador San Pedro is excellent, well located, and about halfway. The Imperial Hotel in Saltillo has become an eye-poker in terms of price and has reduced its rv spaces to less than half. There is one other hotel in Saltillo which has overflow boondocking, I think it is calle El Oasis for 150 pesos.
There is another parador at the toll booth entering the state of SLP. In terms of safe, what is safe anyway? It's like in any rv park, state park, national park, U.S. boondocking, anything can happen. Chances of it happening, slim to none.
People need to get over the cartel thing, we have no stats, no stories, and who would want an rv anyway. What would you do with the damn thing. If people aren't interested or afraid, stay home. I live in a beautiful city that has been destroyed by the media. No tourist has ever been harmed, murdered or killed yet everyone says, "stay away from Monterrey, bypass Monterrey, drive all the way around Timbuktu but don't drive through Monterrey. People have no idea of what they are missing. Shame on the media and the government for publishing such trash. Monterrey isn't any different than Los Angeles, except here they are after each other, not innocent people. As much as I hate the expression, "enough said".
