I was never aware of this, but Fleetwood Mac has a song named after Silver Spring. (Of course, it would be called "Silver Springs")
From the Washington Post:
Stevie Nicks, a singer for the group Fleetwood Mac, wrote a song called "Silver Springs." The title, she said, came from when she was riding on the Beltway and the sign for the next exit said "Silver Spring." The name, she said, "sounded like a pretty fabulous place to me."Emphasis is, of course, mine. My question is, were they driving past exit 30B or 31B?
