A few miles from Hearst Castle, a trash collector spent fifty years cobbling together his house out of junk and found objects. As Cambria became more trendy in the 1970s, neighbors wanted him to tear down the multi-level "eyesore," while others saw "Nitt Witt Ridge" as a folk art monument. It’s still there, and still a controversy within the city and its historical society.
This seems like the kind of roadside construction that would fit in with American Gods’ cosmology. More like The House on the Rock than Hearst Castle, despite the proximity.
And it turns out that the first of Wyland’s 100+ whale murals, on the wall of a Laguna Beach hotel, was later painted over as an "eyesore." (C’mon, really?) But since then, a friend of his bought the building, and he’s recreating the original mural. On canvas this time, so he can move it if anything happens to the wall!
