Roger-
Glad you made it out with your Subie and brought your camera. Here is a link to the thread that Jeremy (xunchicrewx) had over his shots at the the first event:

It contains some discussion on shutter speed and such. Dave also is a photographer and here is the link to his site:

Sorry I could not help you on the slolom until you and your co-driver were through half your runs. We had the situation where the most experienced people in grid were either two driver cars or were close to running when you were. Timing and Scoring actually had to radio to the courseworkers to ask where you were DNFing so I could let you guys know. I am not sure if it was announced, but we usually have a "course walk" with a fairly skilled and experienced driver before the drivers meeting to help explain and analyze the course for the less experienced drivers. If you miss that, you can find me or just ask someone and they will either walk with you or point you to someone who will.
