I have a small collection of minerals in my closet somewhere. A highschool was updating its science department and I was lucky enough to be working their processing for the summer and they let me keep the collection, since it couldn't be sent to anyone like the textbooks could, and would have likely been thrown in the trash. I know, how generous of them to let me keep their trash, but my thought process was "someone else might take them or I'd have to look through a dumpster otherwise"
My favorite rock would have to be whichever one was the last one I gave to my wife. Every so often I'll find a cool one and show her, and she usually insists on keeping them. She has a couple small (definitely not originally for weed) jars she's filling with them. Usually just rocks with quartz inclusions or cool sedimentary lines.
Hey, I live in Ohio and.... That fair.
I hate living in rural areas of red states.
