We had loads of fun spying on the IGAMS (Independence Gem And Mineral Society) meeting to see what other rock clubs are up to.  After all, there’s no rule against being in more than one club.  We enjoyed seeing people’s rocks (Bruce had some nice loot from the Denver gem show), seeing our fellow rockhounds who we usually only see on special occasions, and listening to Mark Sherwood’s presentation on 3D printing.  They also had great snacks.  Meeting in a library is seriously limiting our snacking potential.

Mark Sherwood, the president of IGAMS, gave a presentation on 3D printing. He was printing out crystal models, just like the old wooden crystal models you sometimes see in museums.
