Grandpa's $24,700 backyard coaster triggers zoning fight

A Pennsylvania grandfather spent years creating a private backyard amusement area for his grandchildren, complete with a go-kart track, waterslide and vintage carousel. His latest project, a restored roller coaster called The Tidal Wave, has run into local zoning rules because the township code does not specifically allow such a structure. A court has sent the dispute back to the zoning board.
