I too have a small piece of trinitite.

What?! Is this going to turn into one of those "I was at Woodstock" jamborees? ;^)

Got mine along time ago. I have quite an eclectic pile of flotsam from various places. I have a liquid hydrogen needle valve from a NERVA rocket engine, a mono-atomic layer quantum well imaging wafer, a nickel/iron meteorite, a piece of one of the Martian meteorites, etc. LOL!!

I wasn't at Woodstock (too young), but I have been to the Grand Canyon LOL!
