Several years ago, some like-minded friends and I made a great trip up to Oregon for the annual Prineville and Madras shows. It was pretty much 10 days of rocks, rocks, and more rocks, a trip I highly recommend. After spending a day at Richardson’s Rock Ranch digging thunder eggs, we decided to head over to the Polka Dot agate mine nearby—“just look for the polka dot trailer”, they told us at Richardson’s. Sure enough, after following the directions, we came upon the white trailer covered in multicolor polka dots, looking like a big loaf of Wonder Bread.
