The First Ladies Conference Monday at the George W. Bush Presidential Center on the SMU Campus was a walk through history. With President George W. Bush, First Ladies Laura and Barbara Bush, historian Doris Kearns Goodwin, TV commentator Cokie Roberts, former White House Social Secretaries and Photographers each recalling a special point in time, it was a day to be remembered. A reunion with LBJ White House Social Secretary Bess Abel was especially poignant for David and me.
