Hi Chris - yep - that is more or less the same route and I can do all that with Google as well as other ONLINE maps. I can do it in my phone too. But what I am talking about is some way to map in a COMPUTER while working OFFLINE when no internet is available.
Your map seems to show San Diego de la Union where we both know Dolores Hidalgo belongs - your map seems to show SDdlU twice.
The idea is I can sit somewhere such as Valle de Juarez where internet is often non-existent and I can still go anywhere in North America on my computer maps and figure out roads and routes. I often plan all kinds of ideas that pop into my head about places to go and things to do when we are places where there is no internet. Then I can plan and create a route and save it in my files for future reference - all done OFFLINE in my COMPUTER.
