I remember as a young child going to cross the Causeway in New Orleans on its grand opening. I, being a fidgedie kid with full blown ADD, was tired of the bridge the first mile into it. That wasn't the bad news, when we finally reached the other side, we turned around and drove it back the other way.
When I was a kid, I thought it was the coolest thing in the world that when you were in the middle of the Lake Ponchartrain bridge, you couldn't see land all the way around you.
