Chicago

"When I first came here, this was all swamp. Everyone said I was daft to build a [city] on a swamp, but I built in all the same, just to show them. It sank into the swamp. So I built a second one. That sank into the swamp. So I built a third. That burned down, fell over, then sank into the swamp. But the fourth one stayed up."
