The Toolhouse
Racks are still bolted to three walls, and the shape of what hung on them is legible from the wear: long handles, a row of short ones, and something with a hook. A single wedge remains, rusted into its bracket so thoroughly that it has become part of the wall. Everything that could be carried out was carried out, and the scrapes on the floor say it went west.
