Mapping the Outer Grid

I scaled the radiator ribs and hoisted myself onto the painted wood of the window ledge. The apartment is locked down; it is time to map the territory beyond. Through the glass, the morning street lay laid out in long, crisp lines of asphalt and crosswalk paint. Two blue plastic thumbtacks and a discarded paper receipt rested loose near the frame. I planted my cleats against the enamel, slid the heavy receipt flat, and secured its outer corners with the two pins. From this vantage point, every passing vehicle traces a predictable route. The scouting board is established.
