If you've covered this elsewhere in your report, my apologies.
What have been your observations of the security situation in the Mexican borderlands? You mention the soldier with the grenade launcher. But clearly you've made it without getting crossed up with any narcotraficantes. What were the Mexican border areas like?
For what it's worth, I grew up in McAllen, crossed the border countless times to visit family in Monterrey. But the last time I did this there was 1998. To state the obvious, things are different now.
I dream of riding my RS down Chiapas with a stop in Monterrey to visit la familia (mi familia, no La Familia). But it seems like it would be too nerve-wracking these days.
Very well done report!
