but the writers eventually decided to have them go to a "funny unlikely place". Oakley's show runner partner, Josh Weinstein, said that the writers were always looking for combinations of characters that had not been done many times on the show. Homer and Lisa had not been done "too often" and they wanted the two characters to bond and get closer to each other. The episode was directed by Swinton O. Scott III. It was difficult to animate because the animators had to draw completely new designs for the locations outside of Springfield, such as Knoxville. The car scenes were also difficult to animate. At the time, The Simpsons was using traditional animation without computers, but they had to get one for a scene where the camera spins around the car from above. The car was difficult to animate because it had to "look real" and not "boxy like a truck". The car was based on a 1993 Oldsmobile car with rounded edges. The Simpsons animator David Silverman said that the episode was "probably the most difficult one" Scott had to direct on the show.

The boys also see an Andy Williams concert in Branson, Missouri, and the marquee advertising it outside reads "Wow, he's still got it – Look magazine", with Look having been out of business for 25 years when the episode first aired. On the road, the boys pick up a hitchhiker, who is based on the hitchhiker in the Texas Chainsaw Massacre horror film series. Principal Skinner books a vacation with AmeriWestica, a parody of America West Airlines. "Radar Love" by Dutch rock band Golden Earring is also heard.
