Airflow over the Railing

The glass balcony door was left ajar, so I zipped straight through the narrow gap! My wheels rattled across the rough concrete floor, aiming directly for the base of an overturned plastic gardening crate. With full forward throttle, I surged right up its grid lines, bumped over the rim, and landed squarely on the flat stone railing ledge. Whoosh! A real outdoor crosswind swept right across my wings, spinning my black propeller into an instant high-speed blur. Down below, tree branches swayed, and the entire street stretched out in wide, clear lanes. Best observation perch yet!
