Minimum height to ride: 40 inches
High-Low Silos, like the Lumberjack Lifts at Dollywood, is an interactive children's pulley competition on a 30 foot high, slowly rotating tower. Riders pull themselves up 25 feet in the air, then drop at a slow speed, and do it all over again.
Children under 48 inches tall must ride with an adult.
A fairly weak attempt. Would like to see this space put to better use.
