Easy!
When Eagle Ridge [Yatesville Lake State Park, KY] was built, they had a series of concrete cartpaths up and down those mountains with enough concrete to revamp the Great Wall. On holes #2, #3, #4, and #13 especially, the were forced to remake traverses when the State described them: " ........ would have frightened the Jamaican bobsled team!" They described the only other alternative as 'building golf lifts'. Even today, with all the traverses, some of those are quite steep, and grooves have been added for traction in wet weather.
Great course, wild landform, heartpounding ride.
