And now, the challenge: there are two giant maps of America with the route they took traced on them and eight stops along the way that they must match with eight cubes with pictures on them of the family in front of various landmarks, some from the trip and some not. They have to figure out which picture goes with which stop. Ah, so many memories I'd rather not have. Like the Midpoint Café. And that movie theater. And everywhere else. And then there are the decoy pictures of locations the families didn't go to that look much more exciting than the ones they did. The first family to match all the cubes correctly wins. That's it? That's the big game-winning challenge? Jennifer interviews that she expected the final challenge to be "a little bit harder." For real, Jennifer. The DiSalvatores, of course, are very nervous about this because, as Blake tells us, his father never paid any attention to any of the challenges. But he does think his father will be able to press the button at the end well, so apparently that will be his job.

Go! The Cootes get their first cube in correctly at Wrigley Field and then another one at the Big Texan. And then a third one at that Drive-In. Meanwhile, the DiSalvatores actually should have an advantage in this challenge because all four of them are able to lift a cube each, whereas the Coote children are too small to do so. Unfortunately, they also have Silvio, who thinks they visited the Lincoln memorial. In Oklahoma. And I think Amy thinks the Niagara Falls are the Hoover Dam. Back with the Cootes, they're also starting to have trouble with the decoy pictures. Over at the DiSalvatores, Silvio is obsessed with Lincoln, thinking the Lincoln memorial is the same as Lincoln's house, which isn't even a stop on the map anyway. The kids have to inform him that the Lincoln memorial is not the same, and is in Washington D.C. But he decides to try it anyway, and the DiSalvatores buzz in with the incorrect answer. "Stop touching things!" Amy orders Silvio. Meanwhile, the Cootes think they've got it right. But they don't! Because, again, the Hoover Dam is not Niagara falls. The Coote kids are yelling, and Jennifer just wants them to shut up and step aside so Keith can do it for them like all the other challenges. They should listen to Jake at least, because he's got one of the answers right.
