Met Jack at the York Art Center around 1963 and talked to him there on many occasion, over the years while in art school. Saw him perform at a lounge in east York. Ran into him hiking one time in the Codorus Furnaces area.I would stop and see him every time I was in town and he was always the same hip guy, who could talk about anything. He has a great sense of humor. Condolences to the family.
