Just south of the Rte 8 entrance ramp at Exit 11 in Trumbull, right on the shoulder, is a metal file cabinet, standing upright, as if whoever owned it couldn’t lift it back into their vehicle after they stopped to fix a flat. It is there for the taking. It’s not the be confused with the battered sofa that must have fallen yesterday and was on the New Haven-bound shoulder of the parkway in Wallingford, a victim of a migratory species.
