I'm surprised that JAG and NCIS haven't shown up here for their gross violations of geography. Since they were globetrotting so much, it would probably be possible to generate a long list of problems. There were a number of scenes, though, where Harm was flying his Stearman from an airport near "home" in Washington, D.C. and the terrain seen in the background was nothing like Northern Virginia. The worst offense was late in the series' run when Harm had left JAG. He flew into "Blacksburg, Virginia" and met up with Maddie, who was running a crop-dusting service. Harm went to work for her, doing crop-dusting on the cotton crops. Minor problem -- cotton doesn't grow in the mountains of Southwest Virginia. While we do have an airport here, it looks nothing like what was shown in the program.
NCIS does a pretty good job of being somewhat true to reality with small details, like Virginia license plates that are correct in look but with a number scheme nothing like that offered by the DMV and with the paint job on State Police cars. But they give a false impression of just how close places are to the Washington Navy Yard. The gang jaunts to Norfolk like it is just across the Potomac River and goes deep into the mountains of West Virginia in no time. Apparently the writers in California don't own any maps.
