There were two other Corvettes present (a C4 and a C7) and I spoke to the owner of the newer car for a while. He bought his C7 in September 2016 and has put 64,000 kms on it--bravo! He was about to depart on his "trip of a lifetime," heading down Route 66 to Arizona, but stopping at the National Corvette Museum in Kentucky as well.
There were some peculiar cars that drew attention. There was a 1970 Vanagon, a VW Beetle conversion to become a minivan which looked quite nice. But the weirdest was a first generation Mazda RX-7, which was produced from 1978 to 1985, but this example had its Wankel rotary removed and replaced with a Small Block Chevy 350 V8, a truly time-consuming project but apparently one that is done fairly often. Later versions of the RX-7 have even received LS-series motors (like the one in our Corvette).
