In the middle of Nashville, nearly 200 acres of hills and forest lie undisturbed. Green space along Nolensville Road is a developer's dream, and the owners of the property, Elise and Margaret Croft wanted Grassmere, the name of their homeplace, to remain green and be a place for the study of nature. The Nashville Zoo is looking to make the location its new home. Mayor Phil Bredesen is pitching a controversial plan to move the zoo from Cheatham County to Grassmere. Segment includes audio from a 1964 interview about the Grassmere property. The Crofts donated the property to the Cumberland Science Museum and asked that only education science programs be done on the land.
