Layout revised 30 Sep. A second walk of the perimeter put the zones in their real places: machine rows run from the court-side aisle to the hallway, free weights are past the machine floor, and the strength room is in the far corner by the elevator. The order of machines along each row is reliable. Distances are still estimates (about ±3 squares), and the free weights and strength-room machines are placed approximately. Dashed pins mark spots where a machine was in use and not recorded.
