Whetstone Creek Trail The Whetstone Creek rail-trail follows the bed of a rail spur that once ran from CSX's Tilford Yard to an industrial area at Marietta Boulevard. At present it is only about a mile long, but a future connection to the Silver Comet Trail is a possibility. See Comet Chasers at the PATH Foundation website.       RailGa.com.
