Re: SkyZip at Dollywood!!!
I did the zipline in Ketchikan, Alaska. It was billed as zipping "high over the forest, with views of the wildlife & forest below." It was 7 sections total ranging from 50 feet to 1,000 feet long and the highest was about 200 feet from the ground.
Guess what we saw while zipping? The end of the line! You had to concentrate on keeping yourself facing forward (using one hand positioned on top of the wheel mechanism) and one hand in the "ready" position to begin braking (that hand, thankfully, was gloved). And you were constantly worried about putting the gloved braking hand in front of the wheel mechanism and having it mangled or cut off!
There was no time to look around and, because of your position, you couldn't look below you. No sense of height. No sense of speed. No wildlife.
Was it fun? Yeah, although the most fun was watching the rest of my family -- including my 70-yr-old parents! -- zip across. Would I pay $40 to do it over Dollywood? No.
