We will start at 4PM. It is a walking tour so we will only be at the meeting spot for 5 or 10 minutes. Don't be late.
Bring a jacket, even if it is sunny and warm where you are. SF usually turns very cold in the afternoon/early evening.
My twitter is @sfhandyman You can see my face pic there. I'm 6'2" 190# so I'm pretty easy to find.
