Pieces left by door

Someone left a roughly 4’x5’ sheet of 1” thick MDF (!) by the door. I put this monster in the sheet storage for now, but it will go into the scrap bin in a few days if it’s not taken or tagged. There was also a smaller board (about 2’x3’) in that area. It has a circle pattern painted on one side and a bunch of shallow grooves on the other. I put it straight into the scrap pile because it’s been floating around there for a while now.
