On account of StarFest happening this month I don't think there is going to be a First Sunday Drive (even though it was posted in the MBCA newsletter, no details were sent)
On a side note, this weekend is also the big "Magical Mystery Mini Tour" held by the Redwood Empire Mini Enthusiasts - several hundred classic and new Mini coopers will be taking over the great lawn at Treasure Island and doing runs around the area.
If anyone wants to join in StarFest 2008, please see the other thread I am posting regarding the event (similar idea, open to Mercedes and smart cars)
