Sam, To keep myself from going entirely loopy in the presence of all these Californians, I read the Guardian on-line every morning. Spotted your itinerary and wanted to offer you any info you needed on San Francisco. I've been here for almost 3 years now, so might be able to give you some hints as to what to do/see/ write about when you get here. Let me know if you need any help. If not, good luck on your travels, you smarmy git.
