    OBMS members have a BBQ on the 2nd Saturday of every month. This is a good time to come on down and tour the workshop.  You can start working with stone, on a nice piece of jewelry or that rock you've been meaning to cut while enjoying some good food with good people. 

    Bring a favorite dish that you know everyone will like.  Bring a friend.  Enjoy the warm and friendly atmosphere of fellow rock hounds. Like always, donations are welcome.
