GUTHRIE — Following in his grandfather's footsteps, Hugh Scott stood on the steps of what is now the State Capitol Publishing Museum this morning and fired a single shot. The sound set off a volley of shots from mounted militia dressed like the 4th Cavalry of 100 years ago. The ceremony marked Oklahoma's 100th birthday and was a re-enactment of the moment in 1907 when a pistol shot announced statehood. Scott's grandfather, Dr. Hugh Scott, was secretary to Territorial Gov. Frank Frantz. The grandson used a .45 caliber pistol to fire the shot, the same kind of pistol his grandfather used, except that a blank round was used. Scott never got to know his grandfather, who died in 1940 before he was born. When the shot was fired, the crowd roared and cheered and shortly thereafter followed the re-enactors, who were riding in horse-drawn carriages to the next event, the statehood ceremony.
