Is your dad the Jim Kelso who was a radio announcer? 

My brother Richard McKinney knew that Jim Kelso very well. They attended a lot of races together. Jim Kelso was a great Fred Lorenzon fan and my brother was a Buck and Buddy Baker fan.

I attended a race at Champion Speedway in the late 50s or early 60s and remember Dink Widenhouse winning in a #B-29 car.

Hope this helps you with your inquiry.
