Years later, Trickle commented, "I really do treasure that one in 1966.
There were a lot of behind-the-scenes things that went on there.
Number one, I had never run outside my own backyard, you might say, which is the central Wisconsin area.
I never ran somewhere except in my own little circuit, but I had won there.
The first time I ever stepped out of the central Wisconsin area was to the Rockford Nationals in 1966."

Galbraith claimed that the horse and sparrow theory was partly to blame for the Panic of 1896.

I barely beat the guy that taught me everything.
I'd not seen Dick as much as I'd like to of late.

Could just do magic with the race car and he taught me so much about racing.
