This was my family's dairy farm from 1970 on 19th street in Otsego MI. On the date in 1979 when this airel photo was taken a insulation crew was on site filling the walls of the house with foam insulation which leached toxic formaldehyde gas. This posioned the home and it was inhabitable for over ten years during which my family repurposed the chicken coup as the main domicile until the property was sold in the early 1990s
