Don't be afraid of going to Mex by yourself or in a group. In our opinion it is safer in Mex than in the US. Most of what you hear that is negative are just urban myths---if you want to be afraid, read your local major newspaper or watch the nightly news. We spend about five mos. a year in Mex. and as of last winter have visited every state in Mex and even took a trip to Belize. Basically all you need is "A Traveler's Guide to Mexican Camping" by Mike and Terri Church
www.rollinghomes.com ; it is the bible, they list most campgrounds and how to get to them plus all the info needed to cross into Mex. Second thing to have is a good map, not something from AAA. Get Guia Roji,
www.guiaroji.com.mx Get a guidebook or two.
Regarding insurance we get our through Lewis and Lewis
www.MexicanAutoInsurance.com We get ours on an annual basis. We cancel our liability ins. Stateside while we're in Mex. Get on line and shop.
The joke in Mex about going to Rocky Point, is that it is close to Mexico (like Anchorage is close to Alaska). Kino Bay is fun--you will collect shells without a doubt. Check out Alamos which is near Navojoa--good RV park and nice colonial silver mining city. The Churches book will give you crossing information. We pick smaller crossings and get all of our paperwork done the day before or so in our PU and usually case out the direction of travel for hazards. Our favorite crossing is Naco just out of Bisbee AZ and then Lukeville. If you want any more info, just ask---this is our favorite subject.
