Slanted houses, Tilted houses, Gravity houses, Anti-gravity houses, Mystery Spots, they have many names. Up until a few years ago, I was only familiar with one in Silver Dollar City in Branson, Missouri called "Grandfather's Mansion". My family went to Silver Dollar City yearly starting in 1974 and it was always one of my favorite attractions, especially since I was scared of the roller coaster there, "Fire in the Hole" (it's a really, really tame roller coaster. Okay, I was a big chicken).
Among the brochures I found at a recent sale was this postcard from Silver Dollar City.
