Mr. T, i agree theres no "bad" color combo for a 69 Z if it's restored correctly, or is as original as this one. In fact, the "oddball" colors and combos are usually some of my favorites.
As for supercars at the cruise-in, no, there were no other supercars there, but there WERE some pretty cool/rare musclecars, including numerous real-deal Hemi mopars, and some nice classic corvettes. Yes, many people ask what a Yenko is, in fact, one guy said "Those Yenkos looked almost like Novas"
While many don't know what the car is, I'm always happy to explain the Yenko legend to them, and enjoy all the questions I get. Canonsburg is only about 2 hours from here, so there ARE a few people who know some info about Yenko, at least enough to be dangerous.
One of the most frequent comments I do hear is that it "Can't be real, because Yenko's were all big blocks" I agree the "masses" don't understand or know much about Yenko, or supercars in general, but then again I don't know a ton about Mopars, or Shelbys, etc... The knowledge of stuff comes with your own personal interest. On that note, here's a few other pics of some neat local cars that were also there, I really don't know too much about them, other than that they are cool.
Heres a badass black/red 69 GTX for starters:
