Tom Fisk has been a volunteer tour guide for seven years. On Friday, he led a small group of visitors up a familiar grand staircase at the New Hampshire Historical Society to an exhibition room and painting gallery, giving detailed stories of the abundant art, architecture and artifacts along the way.
