Clear Perimeter

Stood guard by the paint cans as the room went dark. A stack of dry shop rags sat jammed under a rusty socket wrench nearby. Kicked the rags aside to check the hollow behind them. Clean. Pulled an old cotter pin out of the dust, weighed it in one fist, and set it on the rim of an empty can. Solid post for the night. Nobody's sneaking up this flank.
