I can't say I knew who was who or paid much attention to the races today, being obsessed with trying to get some good snapshots. There were also static cars, aircraft and women to ogle, so...
But I was surprised at how serious these guys were- no bumping or accidents, but it was very cool seeing these museum pieces out on the track being raced for real.
I've got one teaser up so far; look for more in the Photos forum.
