They lived at Walhalla until Clarence decided to quit teaching for a while, moved to Bremerton, Washington, where both worked at the Puget Sound Naval Shipyard for approximately four years. Returned to Sutton and purchased the Ed. Bailey farm south of Sutton, which they still own and operate.
Clarence decided a little sidewalk farming would be nice, so they built a home in Cooperstown in 1959.
