Nice article, but I have to say I disliked Joshua Tree and Twenty Nine Palms, would never go there again. Organ Pipes National Monument, now there is a beautiful desert!
I always turn mine off after showering or washing dishes, propane isn't cheap. A few days ago I upgraded my hot water heater to gas, electric, so now if I am at a camp ground that is not metering my electric, I think I will leave it on!
