I need to buy compressed-gas stove fuel (isobutane, butane, propane, fartgas, whatever, etc.) for a Jetboil stove before an Aconcagua trip, and I would like to buy it before leaving town in Mendoza. I have already established that the Jetboil works at high elevation, so that is not an issue.
Specific street directions would be great, but I'll take whatever information I can get, of course.
If the fuel I need is available at Plaza de Mules, that information will be useful, but I would prefer to have it sooner, just to be sure that I have it, and also because I presume I may need it for a night before I arrive at base camp.
Muchas gracias.
