I'd post in the regional forum, but it seems no one ever goes into those.
A couple of us have gone for a drive a few months back, and it was a lot of fun, but at the time there weren't too many delivered cars. But now there are plenty of us! Any other Bay Area 12C owners interested in joining an impromptu 12C rally, shoot me a PM with your email and I'll put something together.
Below is a pic from this past saturday's FOG Rally Media event in San Francisco. 50 Ferraris and my Mac. Guess which got the most attention? Like TexasMongrel - I was surprised by just how many people completely ignored the 458s there and flocked around the 12C. Such a fun event though - lots of great people, and charity for a good cause (Blue Planet Network).
