It was obvious to me even at a young age: A TV movie about killer bees invading New Orleans had the populous seek refuge in the mountains outside of town. Or Murder She Wrote, where EVERY city in America seemed to have the San Gabriel mountains in the background. Smokey and the Bandit II, where the border between Texas and Louisiana is stark and dry, eerily reminiscent of southern California. Even today, Psych tries to make British Columbia (wet and green) be Santa Barbara (arid California coastline). Everything is geared for cheap production in or around LA, whether or not it looks silly.
Of course, a few times they really tried to get it right. Walker Texas Ranger was filmed, in all places, Texas. And I Spy filmed on location in exotic places like Hong Kong, Italy, etc. So somebody had to be aware that the little things count.

Just thought that these shows deserved to be singled out for letting us have a brian.

P.S. The list of atrocities goes on and on. Don't get me started on Aaron Spelling and his warping of geography.
