What would you take into a desert?

The drive was really nice - with all the coloured mountains, the salt flats and the viaduct of the tren de las nubes. Until the strange noise of the car started getting louder, in the middle of nowhere - litterally.
We were lucky, and got towed by a truck - in worse contition than our car - to a cabin at the edge of the salt flats. There we could cook a soup and get some sleep.
Next day, we had to wait half a day for a phone, and another half for a new car.
Caroline, Albi and Christian where excellent buddies in the desert - probably one of my best days in the whole trip. Really.
