Okay, here's one that I have loved ever since I was a kid. I used to beg to go see it. It's a roadside attraction waymark but I also have it listed as a pedestrian suspension bridge. The big surprise is who the pedestrians are. It's so cute watching them use it. Hmmm.... a best kept secret waymark? You'll have to check the waymark out to discover the mystery pedestrians.
Anyhow I had trouble getting a good picture of it so for better pics use the link listed in the variables for Roadside America's shots of it.
