SB: Re: Refridgeration, and tire foundations

["Trkstr" <trkstr@hotmail.com>]

You might want to read the Earthship books with regards to building with
tires and your frig.    They discuss both, although the frig is located
inside the home and uses air drafting for cooling/freezing all year long.

Good-luck on your project and don't be afraid to use tires in construction.
