Glad you made it out okay. I was hoping you'd stay with Vinnie tonight in Concord.
Meant to warn you, don't ever call it "Frisco" as the locals really REALLY hate that nickname. I even remember them catching some escaped criminals, because when they were asked where they were from they said Frisco, so they knew they were lying. SF has a lot of nicknames, but its just The City to most people. The Bay Area is The City, the East Bay and the South Bay.
BTW, if you see anyone on a Vespa scooter with lots of patches and/or buttons on their jacket, recruit them to our cause. They'll be highly sympathetic. And if you're anywhere remotely cool outside the tourist areas, you're very likely to see them, especially in SF and Berkeley. But I'll warn you, they're a wacky, hard-drinking group.

Funny your first day in SF will be Black Friday. Mine was too. I dropped in on Macy's, just because I'd never seen one before (they historically didn't bother with SoCal). Have fun tomorrow!!
