The aerial shot of the racetrack does not match the actual race track used for the remaining shots. The racetrack and grand stands used in the scenes are significantly smaller than the racetrack shown in the opening aerial shot.
When Debra and the writing team go to the race track, they are supposed to be at the "Las Vegas Speedway" in Las Vegas, Nevada. The sequence was actually filmed at the now-defunct Irwindale Speedway in Irwindale, California. While "Las Vegas Speedway" is painted on the wall in the opening shot, this was obviously added by the production crew. The actual name of the racetrack is ("Irwindale Speedway") is clearly visible in the background of several shots.
