Hi Erasmo
Exellent job on collecting all the data from your trips departing D.F.. I just came back from touring Mexico ( what a great country )from Tijuana to Merida and I wish that I have had your data before I started my trip. As I don't have a GPS, I recorded all my data with a Ciclo Master CM 436 Computer. if you are interested I can send you the " Altigraph " of all the stages I did.
