at the USRRC race at Pacific Raceway in Kent, WA in July, 1963 between the GT race and the Sports Car Race and that is Dave MacDonald with Carroll. Team Shelby brought three Cobras. They took 1-2-3 in the GT race. Dave finished first, Ken Miles finished second and Bob Holbert finished third.

They also competed in the Over 2 Liter Group in the Sports Car Race where Dave finished 5th in group (6th overall), Ken finished 4th (5th overall) and Bob finished 3rd (4th overall)

I had forgotten that I'd posted this photo of this truck once before, a couple years ago
