I love listening to old airchecks where the prize is something like a dollar
and a half. They'd give the winner's name and street address out on the air.
Sometimes their phone number. In the '60s they used to have contests where
the object was to go knock on people's doors looking for something or asking
if this was the secret house. You'd get shot today. The "Mr. Whisper"
contests were popular too, or guess the record played at a different speed.
Sometimes they'd give way the entire Top 40 of that week on 45s. That must
have set the stations back a bundle.
