We had our first First Monday Rock Swap at the lapidary in August and again this month (October), and everyone had fun looking over and trading rocks at the HGMS Education Center (7801 Bailey Cove Road SE, Huntsville, AL 35802) from 6 to 9 pm. The next meeting is Monday, November 3rd, 6 to 9pm. Bring rocks to trade or just come down to see a lot of interesting rocks. Have yours identified! –Anthony Zwilling
