Thanks John. This type of information sure helps point someone, that lives
in the sticks, in the right direction. I live close to a town that just
got a MacDonald's, so we are not in the stone age, but close. Ask about
polypropylene and they point in the direction of AREA 51. What company
carries polypropylene sheets that you can recommend?
Thanks, Dale.
