If you ever get the chance to go to monterey historics... do it. I can't wait to go back. These are from a long time ago, but as I was looking for a pic of LeMontsre, I found all these great engine shots.. there's something for everyone there.
I used to live in the S.F. Bay area and frequented the Historic Races. Best event in the whole weekend. Easily tops Pebble, Concorso, etc.
