I live in the east bay and I am thinking about checking out this cars and coffee event at the blackhawk shopping center:

I guess they have it the 1st Sunday of every month. I have never attended so not sure if there are a whole lot of cars or if there are even any other beemers. Figuring there are probably a lot of classic and American cars.
