Nope. Not me. No way. No how.
I'd be dead at the thought of it. I froze in the St. Louis Arch and that was inside.
Handrails? Those aren't handrails... it's chicken wire and a little cable. I don't even like glass-bottomed *boats* let alone a wire-bottomed "bridge-like thing" that isn't really a bridge, some hundreds of feet off the water. Nope... no thanks.
I don't even think I'm abnormally fearful of heights. It's just that gravity always wins. As they say: It's not just a good idea. It's the law.
