A method of locating an object includes receiving a wireless signal and raising a marker above a surface of the object. The object can be a mobile vehicle, such as a car, a truck, a motor home, or a motorcycle. The marker can be a flag or a ball. In one embodiment, the marker is coupled to an end of a telescoping rod and is moved by extending the rod, by alternating extending and contracting the rod, by rotating the marker about an axis of the rod, or by any combination of these. Alternatively, or additionally, the marker is swung in a pendular motion above a surface of the object. In still another embodiment, movement of the marker is accompanied by an audio signal, such as chirping or any other distinctive sound.
