Mike tells the prospective builders to drive west on I-70 in Colorado and stop at a certain milepost. While the geography is mostly accurate for the area, it shows a two lane (one in each direction) roadway. I-70 in Colorado is never less than at least two lanes in each direction. However the viewer does not actually hear the directions that guide the driver to the mile marker. Mike tells the first guy to head west on 70 and he will call in 20 minutes with more instructions. It would stand to reason that they would do the pick up in a more secluded area than on the side of a very busy interstate highway.
Colorado never had a six-digit white on green license plate series that started with numbers. Since this show takes place in the middle of the first decade of the new millennium, the plate should have been the green on white series that's still in use today. Despite the error in the registration number, the six-digit white on green plates were discontinued in 1993 and replaced with seven digits starting with letters until 1999.
