Well, somebody went.
There was one Superformance, red/white with a Roush 427R. One silver with black stripes, pretty good looking build but I couldn't tell details. One silver one, pretty low-end, bolt-on wheels and squared-off rear flares... old Shell Valley, maybe? Those were on Rotten Row outside the concours. Across the street, just visiting, was a nice, well-weathered Cobra, black or midnight blue with white stripes and several Western States and NorCal stickers on the windshield.
Highlight of the show was the Enzo, I think. Couple of nice Panteras and two GT350s and a Tiger. No other Shelby/Ford stuff of note.
Might buy a slot in Rotten Row next year.
