One of the last things we did at WonderWorks in Pigeon Forge was the ropes course. You get in a harness and you get attached to a giant web of metal railings. That way you can walk across these platforms and ropes safely. Even with the safety harness, this did scare me a bit. Heights and me don't get along. There's actually three levels of this, but I only had enough energy and courage for the lowest level. What's kind of neat is that this ropes course is actually hidden in plain sight, I never noticed it when we walked by it the first time.
