Africa Northbound September 1975. Leaders Freddy Glaser, Bob Sheldon, Alan Townsing and latterly John Scully.
Does anyone know how/when Bob Sheldon died? Several of us from his southbound trip preceding this one (March-January 1975) are having a reunion in 2020 on the 45th anniversary of departure. Any information will be much appreciated.
