In 1964, Walt Disney came up with an idea for an indoor roller coaster that would be a revolutionary experience for his guests. Unfortunately, Mr. Disney's ideas far outpaced the available technology. Disneyland management suggested just building a simplified Matterhorn indoors might suffice. That wasn't good enough for Walt, who insisted on saving the idea for later. The cut down Space Mountain was eventually built in Florida's Magic Kingdom, but the technology to build Walt Disney's dream had finally become available. In 1977, that Dream became reality in DISNEYLAND.
