We stayed at the KOA and went to the KOA mines across the street. My Gson and wife liked looking for the diamonds. I found more along the stream than in the mine itself. They only blast once a year in the spring to unearth new gems, so that is probably a better time to go. I am not a KOA kind of camper but this one is nice, had a site right on the river. Gson caught one trout, all and all a good trip. If I went back I would go to the Ace of Diamond mine right next store as it is a commercial working mine and they blast and move rock every day and I think it would be easier to find more gems there. Thanks again for your recommendations.
