Daryl - last year a number of us met at Ikeda (no not Ikea) at the Foresthill exit (just east of downtown) and then left onto Lincoln Highway a couple of blocks. There is a Chevron and 76 station at that exit for gas and Mini-mart. Here is the link.

I would suggest the SJ area guys coordinate a meeting spot and time that works for you. The overall group just has to decide if Walnut Creek works and when. We still have time for others to pipe in.
Dino - as we come from Burlingame, we could meet at OSH in Foster City about 60 minutes before expected departure. That should leave enough time to fuel up in Walnut Creek prior to meeting. Will that work for you?
