Many years ago there was a theme park in San Jose called Frontier Village. It had a western theme and was inspired by Disneyland, but never gained enough traction to survive despite having a number of interesting attractions (including gunfights and a roller coaster). A San Jose resident named Shaughnessy McGehee has been collecting and recreating elements of Frontier Village over the years, but is now moving out of state. His vast collection was split among the New Museum of Los Gatos and Great America and the first showing of the collection is already on display in Los Gatos.
