From Day 11: Mississippi, Louisiana, and Arkansas. Before I could board the MV Mississippi IV, I had to work my way through the Lower Mississippi River Museum. Among the usual exhibits, it also had a few interactive exhibits, like this one how floods work... and how to make one. Even while playing the Sims, I never imagined making a disaster. Needless to say, I felt guilty while trying to make a flood, especially having escaped one myself, so I stopped.
