Slightly off topic, but how come you were going on a multi-hour drive anywhere with no water, let alone into a remote mountainous area on a hot day? I'm uncomfortably aware how quickly vehicles take me to inconvenient, if not dangerous, distances. 10 miles away is a short distance to drive but three hours to walk. Even fifteen minutes on a bike is a tedious walking distance back if it breaks down. For how easy it is to put or keep some bottled water in a car, why not do that all the time?
