On a related note, anybody got a rock polisher out there and/or doing rock cutting? I have a lot of lake Superior agate. I could ship some. You could keep a share in exchange for polishing some.
I've dabbled in the black arts of prospecting a bit. Found some very interesting semi-precious stones and mineral specimens when I worked in New Mexico for awhile.
Found a lot of native copper in the UP of Michigan. Lake Superior agate is my bread and butter. I find the best ones in gravel...
