Largest river steamboat ever built. I took much better pictures of it, but here's the story. It was leaving port, playing it's calliope music, heading downriver, when one of the stacks started to fall over. I was freaking out, running alongside, taking video, certain there was about to be some kind of catastrophe. There were other people around, and when I said "LOOK at the stack!" a man nonchalantly informed me that they have to put them down to go under the bridge. Huge head-smack moment, LOL!
