The X-Files episode supposedly set in Atlantic City, NJ was a real thigh-slapper for anyone familiar with the area.

(I remember they had the forest of the "Pine Barrens" -- being played, of course, by the entirely-different-looking tall, straight pines of the Pacific NW -- running right up to the city limits. This is... difficult, as Atlantic City is in fact an island, and the forest stops quite a long way inland to make way for extensive salt marshes that give out into the bay that separates the mainland from Atlantic City itself. Good times.)
