Not the biggest or the best, but one I happened to drive by while lookin' at houses. "Up The Ridge" from Paradise, Magalia is a town of about 18,000 scattered among the pines and oaks. POA is a housing association and the car show was at their meetin' house and pool area. Actually, a pretty nice HOA for a small place and less than $300 a year to belong to!
Anyhow, this was there pancake breakfast and car show. I got there at 8am and it didn't start till 9, so there weren't much ta shoot. Aw, shoot.
These are all with the 30D, no flash, 24-105 stuck on the front.
