I'm a star
You seem to know way more then me on this subject so I’ll have to take your word for it.
I always had a passing interest in rocks, but I've been learning a lot about them lately. I think it's the lack of intellectual stimulation of the job. I do it partly out of the treasure hunt aspect. I don't want to be one of those guys with a specimen worth a fortune in his collection without knowing it. A lot of stories out there like that.
