Can you do the weekday rides that go around PV? I forget what day(s) they are, but they meet at the intersection of Page Mill and Junipero Serra/Foothill around noonish. I think it's the AV ride so if SteveE sees this, he might be able to fill you in on more details. It's a pretty big group, so I'm pretty sure you'd be able to hang.

Edit: Sean, here's a link to a bunch of training rides, the one I was thinking of is the "Noon Ride - Palo Alto" one, and it meets at Page Mill & Old Page Mill, which is just a little west of the intersection I noted above.
