      Club Chat
      I went to the rock show in the parking lot last weekend, one of the ladies showing there said there would be something going on at Krasl in St Joe this Sunday. BUT there is NOTHING on their website about this. I tried contacting Krasl last week and no one has answered. I don't want to go down there if nothing is going on. Thanks.

      Hi, I have a 5-gallon bucket of polishing grit. It is 3/4 full. I do not know the size but would like to sell it.

      In search of moqui balls
      Club Chat
      Hi, everyone, my grandson, age 10, often opens my rock case to look at my moqui ball. We searched for one for him at the rock and gem show, but came up empty. One vendor gave me his card and told me to check with him later. Unfortunately, I went to call him this morning only to find that I had been holding on to the wrong card. Can one of you help me out? Hoping for a Christmas present. :)
