Getting to Barra de Potosi

Padrino, I couldn't agree more. My wife & I have been traveling to Mexico for years. I only carry small denomination peso currency & coins.

As far as courtesy protocol is concerned, when traveling outside of the U.S. it is tantamount to being in someone else's home. Thus, respect for the people & the culture is a top priority for me. And part of that respect is communicating in the host language as best as possible. As far as communicating in Spanish is concerned, my wife is of Mexican heritage & speaks the language fluently. As for me, I know enough of the language to communicate reasonably well when speaking English is not an option.

Again, you offer sage advice to travelers.
