In reply to Helen Gibson Hoey: In Peru and Bolivia you can get this clear alcohol in plastic bottles which is used as fuel, similar to meths and I used it is a trangia when I took it there. Lots of the miners in Bolivia also drink it. A trangia though, really struggles at altitude and a lot of the area around Huaraz is massively high. Mine completely failed on one of the mountains near Arequipa. Luckily someone had one of those jet stoves, they work anywhere and burn any fuel you choose to put in them. It might be worth investing and I'm sure could get one out there for less than you would pay here. Have fun, wish I was going.
