Friends:
I am racing my 1970 Porsche 914/6 GT in the Sonoma Vintage Motorsports Festival at Infineon (Sears Point) Raceway the weekend of June 4 & 5. This is one of the top vintage race events in the US, with 400 race vintage cars and two days of racing. I am in Group 3 B.
There is full spectator access to the paddock where you can see the cars up close and visit with the drivers and crew, as well as great food and wine and racing stuff enough to satisfy every racing fan. It really is a lot of noisy fun!
Here is the website for the event, which explains all of the particulars.
