NAD built a roller coaster in the country of Guatemala in the late 1940s or early 1950s. This was a ravine coaster and it has been said "workers had to dig 38 feet out of the side of a mountain to get the right grade. " It was over a mile long and lasted only a few years as the new government used it for firewood. What the name of this park was isn't known at this time. In 1973 Aurel Vaszin sold the company to a Toledo firm, which renamed it the International Amusement Device.
