I'm a big fan of rocks. I often collect and study them at national parks.
Hello, that is awesome. Do you know about geology?
I do, but I'm a bit of an amateur. Yourself?
I am as well, It's know as rockhounding in the USA. It's quite common really.
Do you have a favorite kind of rock? I know there's supposed to be 3 main types.
 It is amazing that people collect rocks for a hobby.
It's important to have hobbies that are both entertaining and educational.  
Yes there are many clubs and groups that are just for rock hunting. 
A handy tool for finding a club near you is rocktumbler.com. I found more than six in my home state alone!
