This fantastic event takes place the weekend prior to the Pebble Beach Concours and it allows participants in the actual Motorsport reunion time to test/tune their cars as well as participate in short race events. Here is a Bugatti Grand Prix car navigating through the Corkscrew. The paddock of Laguna Seca may not be completely full for this event, but there are significantly less spectators so car watching is much easier than the following weekend.

McLaren F1 GTR in the paddocks.

Mercedes 300SL cooling off.

The mighty Porsche 917.

There are even some good finds to be made in the parking lot, such as this longhood 911.
