That would be KDWB and that radio station is still here. I went to some of those events that they sponsored. I would have been one of those taking a look for sure. A 440 in an A body was about as mean as you could get back then. You could stand behind the cars while they were doing burnouts. I remember getting a lot of little black bits of rubber and crud on my white t shirts that I always wore. Lol. I probably saw your dad run at some time or other.
