Okay. I've done some crazy things in my life, and this is right up there as one of the coolest I've done. In Sydney Australia, they allow you to climb The Harbour Bridge for a $200 dollar fee. And we're not just talking the bridge in itself, but rather climbing up to the very top of the arch! At times I was a little scared with nerves. We did the last climb of the night, so we got to see the entire city lit up. If you have time, it's worth googling The Harbour Bridge if you're not familiar with it. It's the worlds largest span on a bridge. The view was spectacular, and I'd do it again in a heartbeat.
