In 1986, the Federated Women's Club provided the funding to build the Gazebo at the Arboretum. It was designed by Glen Cullor, then an engineer at Boeing. He and his wife, Peggy, a member of the FWC, were prominent supporters of the Arboretum. The Gazebo was built by "the husbands." One assumes that Milton was one of them.
This photo was taken in the early 1990s, before trees in the greenbelt began encroaching on the view of downtown Seattle. The students pictured here were taking part in a plant ID class.
