The EESCC held a "fast grass" autcross for members only back in October of 2004. It was fun, but very rough. A few folks popped the beads of their tires off the rim, an example is the VW at the bottom of the page.
Sean had top time for the morning half of the day, but opted out of the afternoon runs.
If you want a higer resolution original version of any of these, Sean can get it to you. Thanks for the great photos Keith!
