I know this house! The woman waving on the front porch actually died, leaving behind her elderly husband. He was so devastated when she died, and he became kind of a recluse. The government wanted to tear down the house, so he got a bunch of helium balloons and lifted the house away to go live by a waterfall or something. Also there was a boy scout and a talking dog for some reason. I don’t know, I could be remembering this wrong.
