Sorry if there's already a thread on this...but if there isn't, then I'll begin with this one:

In one episode of Adam-12 titled "Log 74-Light Duty" [[originally aired 3/21/1970), the officers are visited by a man and a woman, both originally from Detroit, but later moved to the show's setting, Los Angeles. About 18 minutes in, the man says that he went back during a vacation the year before-he said that it was a mistake and that everything had changed-he says that his street didn't even exist any more [["Sycamore on the west side"-but as of 2014, there is still a Sycamore Street in the city-which, coincidentally, is on the west side-specifically, branching off Grand River one block south of MLK and near the Motor City Casino). The woman then said she knew it well from the big trees that lined it and he replied that these trees were also gone.
