I spent the day at lime rock park in upstate CT friday just hacking around and taking pics.
It's a laid back atmosphere the day before the race - lots of practicing and qualifying - you don't quite get the richness and pageantry of race day, but it's easier to move around and get pics, besides, I got good race-day shots last year, all I wanted to work on was my panning, I did better this year.
