It's the Gold Prospectors Association Of America Gold show. It's a chance for people to come and learn about mining, be it Metal Detecting, dredging, panning, highbanking, etc. It gives Venders a chance to show what their products can do. They also have experts in the field come and teach / Lecture. A minelab rep gave a talk on Metal Detecting (not Minelabs) that was outstanding. I now have a little better idea about how to detect for Gold nuggets, very very very slow. I also have a better understanding of coil signal and a lot of other things he talked about that by tomorrow I'll have aclean slate to learn it all over again.
Here's some information and city's/dates. http://www.goldprospectors.org/EVENTS/GoldTreasureShows/tabid/62/Default.aspx
