Tru,
I can't find any of the silver tarps at the hardware stores around here so I just get the cheap green ones. They block the sun and it is dark under them and between them and the house. I asked last year about a silver one and they said they couldn't get one. I am going to drive over to a larger store on Twin View today and see what they have.What I need is a huge air bubble like they make to store cars in that will cover the whole house.
As for Steve's Nitros Engine, he will have to answer that. My guess would be he had it built so he could add a shot of nitrous to it, but that is just a guess.
Warren,
I have been to Death Valley several times and spend time in some of the area. Burn to death in the day and freeze in the night. And yes, it does get cold at night in the desert. Don't believe everything Hollywood puts in their movies.
