Cub Scouts

Hello - I am the den leader for a local cub scout den here in Ventura and we plan to attend the Gem show next weekend at the Oxnard Civic auditorium. How/who would I get in touch with so that I might get the most out of this for my boys? There are certain qualifications for the boys to earn their Geologist badge and I know that attending the show will give them opportunity to fulfill many of the requirements. I would appreciate any contact information or otherwise that you may have to assist me. Thank you.
