Stopped at exit 59 off I-75 Ga.(Love's Truckstop) While walking NW to thebuilding a flash of light to the west attracted my attention. The object was approx. 2 to 4 miles west and perhaps at 4000' in altitude. It was traveling due north. The object was silver and was reflecting the morning sun. It also appeared to be tumbling as the flashes were irregular in frequency and duration. The object was visible between the flashes and although I could not determine a definate physical shape it could have been triangular. After about 45 seconds the object turned to the NW and shortly after went out of visual range.
