I decided to start this group to share and spread knowledge of Rock and Mineral Collecting. It's a FUN and VERY INTERESTING hobby, it is as challenging and rewarding as you want to make it and it even has investment potential. Please join our group, share the knowledge you have about something and learn about something else, there's soooo much out there. And new things are being discovered constantly and often times by ametuers.

We are one of the largest and most active Chicago book groups. If you love discussing only the greatest books being published in a wide variety of nonfiction categories (psychology, history, memoirs, politics, personal growth, economics, nature and beyond), sign up now!
