The Cootes pile into their RV and set off for their reward. Things aren't so happy in the Katzenberg van, as Marc says it hurts to lose. Sami says that they lost because they went into the challenge being too cocky. The rest of the family tells her to be quiet, even though she's right. Over in the Faverey RV, the kids are fighting. Ashley throws a temper tantrum over gummi worms, which is sure to come back and bite her in the ass when her classmates see this.

The DiSalvatores are stuck parking next to the Cootes at the next stop. Amy admits that because of her outburst, this is awkward. Amy walks over to the Cootes and apologizes and seems to smooth things over with the Cootes like an adult. But the Cootes are babies, so they act like they're cool with Amy when they're really still angry. A fire truck arrives and Madison Mayor John Hamm, III, pops out and says it's the Cootes' ride to their reward dinner. It's not on a riverboat like I expected, but a narrow bridge with a table set up in the middle. Unfortunately, they have to eat with the mayor and a woman I'm guessing is his wife, which is kind of awkward. What are they going to talk about? Madison? Road trips? These people have very little in common.

The next day, it's time to leave Illinois for Mississippi, as Dee Faverey reads it. "Missouri!" the rest of her family corrects her. Poor Dee is not pleased to make a reading error on national television. The RVs cross the bridge the Cootes ate on last night and pass that arch thing in St. Louis, where the End of the Road challenge awaits the three losers. The challenge for each family is to take a giant inflatable ball and roll it under a series of mini-arches to the finish line. The family that does this slowest is off the show. Also, each family must choose one person to sit inside the ball. Obviously, it'll be the smallest. Time to watch Hyleri fight with Sami over who weighs less! And also again, the ball is tethered to a rope of a certain length so that the family has to maneuver the ball through the certain path of arches, or else they'll run out of rope and not be able to cross the final arch.
