To John G. and John R.,
Thanks, guys, for the information on the various map sites. I found the Maps of Mexico link on the Nuestros Ranchos site works best for me. So does the MSN Maps (the old one with just maps, not the new one with the satellite photos).
The satellite photo image maps don't work for me, one, because I have an extremely slow dial-up connection, and two, the satellite maps only show the topography---there are no border lines or name labels for towns and highways, so I can't relate to where a place is unless I can see where the larger municipalities and major highways are. It must be nice to zoom in and see buildings, but the e-local Municipios de Mexico website has photos of the major buildings in each city, plus history, coordinates, etc.
John (Gonzales)---it was great you could see your grandfather's house near Jalos, but it must be because you are so familiar with the topography from having been there. I wouldn't have a clue as to what I was looking at.
Thanks again,
Emilie
