Walnut Grove was demolished!
Michael Landon refused to let Walnut Grove become a set for future projects and thus had it demolished. This is sort of the opposite to the idea of creating sustainable cities, like the one featured in Little House on the Prairie.
One Walnut Grove home was saved!
That home being, of course, the Ingall’s house. Unfortunately the home would be destroyed in a wildfire back in 2003. Guess it was meant to be destroyed.
