We will be hiring a car and driving through Death Valley from LA to Furnace Creek, staying a night then driving on to Las Vegas. Anyone have any safety tips for this trip through one of the hottest parts of the world, a trip we are doing in the hottest part of the year? I am starting to think we are crazy although the area looks spectacular from pictures I've seen. What do we do if our car breaks down??? Our mobile phones will not work in the park. Anyone done this trip?
