my best run was 151.7 mph in a stock 2010 Grand Sport MN6.
Altitude approx 2800 ft, air density equivalency reported at 3800-4200 ft.
Cloudy and cool, very brief light rain late morning.
About 100 participants, no injuries or major mechanical failures.
The event was well organized and well managed.
The organizer announced intentions for a 2-day repeat in early October.
Participants included MANY Corvettes, a dozen or more Ford GTs, a few Porsches and a 1958 Volkswagon.
A beautifully restored 1936 Indian motorcyle, a dozen+ street bikes, and a few racing bikes and race cars rounded out the field.
A few of the bikes with NOS were trapping just a hair short of the 200 mph mark.
LS3s were trapping the mile in the mid 150s, Z06s were in the 165 range, and the new ZR-1s were hitting close to 180.
