I'm travelling down to Mexico to climb the "Trilogy"- Nevado de Toluca, Ixta, and Orizaba. I've decided to go with the Jetboil and pocket rocket for stoves, and need to know where I can buy fuel cannisters down there in Mexico. I was hoping to not have to go too far out of the way in order to re-supply. We'll need to pick some up after we get down from Nevado de Toluca- before Ixta. Unless we want to carry lots of cannisters from the beginning of the trip, we'll need to re-supply again before Orizaba.
I was hoping to avoid backtracking all the way to Mexico City.
Also: Where did you find the best places for re-supplying on food?
