Factual error: When plotting the trip to Detroit, it show Frank drawing his route as I 80 merging onto 75N in Toledo toward Detroit. Toledo is approximately 60 miles south of Detroit. When actually driving, they stop at a HoJo's and pass a road sign that says Columbus 64, Dayton 86 and Detroit 212 on I 75.That puts them going north on I 75 between Cincinnati and Dayton. That would have put them 160 miles south of I-80.
Suggested correction: The sign read Detroit 272, not 212. Doing a radius from each point creates a convergence of three circles pinpointing their actual location. That location is in the small town of Sparta, Kentucky.
Other mistake: In the movie it is said that they're going to fly from Port Charlotte to Detroit, then drive to a meeting and back in three hours. Port Charlotte is in Florida. That timeline would be impossible. They meant Port Clinton Michigan.
Suggested correction: They never said Port Charlotte.
