Apparently there is a weird thing about Streets & Trips that sometimes it will show a location at one scale or zoom level but not at another. I finally found Santa Cruz and tried to zoom in but it disappears. So I zoomed back out and highlighted it and zoomed back in and it stayed. But thought S&T shows many towns streets it does not show that town that I can find.
Thanks for all the tips on the route. I was pretty sure I knew what to do but then got confused.
Here is a web address . . .
http://www.sct.gob.mx/informacion-general/planeacion/atlas-cartograficos/listado-de-atlas . . .
which is the official SCT MX Gov't website for maps. These are the maps Guia Roji gets there maps from but these are more detailed. If you download these to your computer you will find you can zoom in and move around to look closely at the map area you are interested in. These maps are .pdf files and can be quite large - the site is not fast so can take time to download. But better than Guia Roji in a number of ways - if you can read them on your computer. They show many things Guia Roji maps do not show but then Guia Roji may have something the SCT maps don't have.
I am not sure what is going on with recent versions of Adobe Reader which is used to read these .pdf maps. I cannot find the Hand Tool I used to use to grab and move the map around to the area I want to look at more closely. Maybe the Hand Tool is there but I have the latest Adobe download update and I cannot find the Hand Tool. I can easily Zoom and scroll and move the map around other ways but cannot find the Hand Tool. These are very good maps but using them can take a little practice - like anything else.
Here are some interesting comparisons I noted when comparing my 2010 Guia Roji to the SCT maps which I think we updated in 2011 - and also to my 2013 Streets & Trips.
There is a road on the 2010 Guia Roji going to San Blas they show as MX54. The SCT maps show this road as MX200. On Streets & Trips this same road is difficult to find but they show it as MX74. I think. Can't be sure about any of this. And therein lies the problem with trying to find our way around Mexico. Some maps show there are more roads than other maps. Different maps show different numbers for the same roads. Some maps show a road as an unimproved road and another map shows it as a super-highway.
Then, as someone noted above, the sign you need to find to take the correct turn to get to the road going to where you want to go could say something other than what you think it should say. It takes a bit a practice and a lot of map reading to find the best routes around Mexico.
All of which is why we have all the maps - and both a Garmin and Streets & Trips. I try to always check with the SCT maps too.
As an added note and something most recent travelers in Mexico know - they have been doing some amazing things with new roads as well as rebuilding some of the old roads to be much better than they were just a few years ago - and many new perifericos too. So asking who has been on this or that road recently is the only way to know what is going on with that road this week - it could change next week. Not all roads or perifericos can be found on any map.
