On the subject of gas. Here is our spare gas setup and our gear being sent along on a chase vehicle. These Chinese gas cans cost 50 pesos each and both started leaking on day 2. Next time I drive to the US, I'll get a good DOT approved gas can. There are "litros de gasolina" available in some of the small ranchos, but it is convenient to have our own. We don't have to look for gas, we don't have to wait in line for others to fill up, or worry about the litros running out, and we have the higher octane "roja".
