Greyhound hits the century mark

To commemorate its 100th anniversary, Greyhound Bus Lines is launching a “Centennial Tour” made up of two buses converted into "mobile musuems" that will visit 40 cities across the U.S. over the next six months -- a tour that will also feature various "classic coach" bus models from Greyound's past. The tour recently stopped in Washington D.C., participating in a special media event at DOT HQ. (All photos courtesy of Greyhound and The Gillen Group.)
