Walking with Superman: Day 44

Superman's at the southern tip of Illinois, where he finds a surprising town called Metropolis! The whole town sells Superman memorabilia, they're having a huge Superman celebration, and there's even a Superman statue in the town square. Superman is flattered to be sure, until he realizes that everyone in Metropolis thinks "Superman" is a fictional character! What's more, the townspeople think that Superman is just an actor named Josh Boultinghouse, hired to play the character for the event! How can Superman convince this town of the truth, and how can he leave knowing that over six thousand people know everything about him? What is the strange secret of the second Metropolis?
