You bring up a very important point that is not apparent or obvious to the many visitors to this board that don't work in radio: stations serve markets, not cities. "Markets" in radio language are sets of counties, not cities. Some markets have a dozen or more counties like Houston or New York City. Some are just one county. But no market is a "city" by itself.
Paul Drew told a great story about coming to program KFRC in 1970. He was unsure how to program to a sophisticated market (he'd done Atlanta, Detroit and Philadelphia).
On his first weekend, the sales manager gave him tickets to the 49ers game, which was at Kezar Stadium, built in 1925 and then crumbling (the Niners would leave for Candlestick the following year).
As Paul put it: "I got to see the people. This wasn't Nob Hill---this was Milwaukee."
The lesson he learned was that it wasn't all about the city. Working-class and middle-class people were not that different from what he'd seen elsewhere. It probably played into his decision to hire Dr. Don at KFRC. He knew.
And from ten years back home in California, I'll tell anyone who asks----you get more than about 25 miles inland almost anywhere in California and it gets real red-state real quick.
