Here is a map that shows the roads and towns of the posts that you have been seeing. I have around 3 more posts going up the Baja and thought it would be nice to see exactly where the different cites were. Some have asked would you go into Mexico again without the security of a tour group. The only reason we used the tour group was for the security. Now after the trip, we would still not go in on the El Paso side, but we would do the Baja to Cabo. That's a 1000 mile trip one way. The roads are well marked, although very narrow, with many drop offs on the curb side of the roads. There are lots of PEMEX gas and diesel stations along the way. There are some rules you have to follow but if you do your research you would have no problem on the Baja side.
