Just got back from putting a thousand miles on my roadster over 4 days at the 10th annual Michigan Mille. We were based in Traverse City this year and sponsored by Haggerty Insurance and Auctions America (RM).
My car ran with numerous Porsches, TR-4 & 6, 2 Ferraris, 2 Tigers, 240Z, Healy 3000, a Bricklin, '35 Bentley, etc... 46 cars total.
Also, found lots of non-ethanol gas in northern Mich, and it really makes a difference.
Here's a Saturday a.m. departure pic from the Chrysler Museum
