At their next stop, Des Moines, Iowa, airport officials do not allow Wyatt to board the connecting flight. So they decide to travel to St. Louis, Missouri to board another connecting flight. En route to St. Louis they have an argument which leads to an accident which ends up with their vehicle falling into the river. They have dinner in a cowboy diner and then try to run out on the check, but get arrested. After posting bail, they are let off and once again happen upon the delivery truck outside a diner. While the deliveryman is having dinner, Wyatt decides to empty the truck's gas tank in order to stall him, but a carelessly flung cigarette butt sets fire to the gas and causes the truck to explode. But even that doesn't stop the deliveryman (who is clearly over the edge by now) and he drives off. Wyatt and Ivy then steal a drunk's car and drive to Kim's campus.
