I think it was 1986, after building a goat house (pictured below) for a homeowner/goatowner/goodfriend in West Concord. She asked me to build something for her goats to climb on. They really liked this thing. They would hang out all day, on what I like to call The Goat Fort.
These goats were really cool. I still remember each individual one. They were real characters.
