Periodic 9:14 AM breakfasts. Luke said he would likely be calling another one some time.
Other than that, we have at least 4 PCA regions in the area (depends on how you define "Bay Area", could be more).
The Zone 7 map/list will show you:
http://www.pca.org/Regions/RegionDirectory.aspx?Zone=7Golden Gate Region is the main one on the Peninsula, and in theory all of Santa Clara County.
http://www.pca-ggr.org/Loma Prieta Region actually has most of its members in Santa Clara County. That's my region, too.
http://lpr.pca.org/Diablo Region is in the East Bay. They have weekly (?) breakfasts in Dublin, I think.
http://www.diablo-pca.org/Redwood Region is in the North Bay.
http://red.pca.org/All of the above but DR run autoX events. Some are down at Marina (near Monterey), RR uses the Sonoma County Airport in Santa Rosa, and sometimes we get to use an aircraft parking area (HUGE!!!) at Alameda Naval Station.
The Zone 7 calendar shows most Region events in the Zone as well, so it can be a one-stop shop:
