Around 1985, my buddy & I stumbled upon an abandoned junkyard in eastern PA somewhere. I say 'abandoned' because there was no fence, no gate, no border, no buildings, no signage, no evidence of scrapping or moving them around & it was all overgrown. Looked like occasionally they'd tow a car in there and just leave it in the patch of trees. We wandered thru it, and there was a double-sided porcelain dealership sign there; DeSoto-Plymouth, about 4 feet in diameter and 8 or 10 inches thick, circular, and some of the neon lettering was still on it. I suppose if one of us had access to a truck, it would've followed us home. At some point in the '90s the whole area was cleaned out & I have to believe it was all crushed/scrapped. Man, I wanted that sign.
