A few days after the fire, the sign was still there and I decided to go get it. My neighbor Barry and I drove over in his van with a Sawz-all. We cut it off the 4x4 struts in the ground, and carefully unscrewed the metal off the burned 2x4's.
It had received new graffiti in the few days between the fire and my getting it: a dark red squiggle and a paint marker reading "ICE GTFO".
I reassembled it onto a new wood frame in my studio, as seen here.
