San Francisco Trip soon

Hello Everyone, First post on here and glad i've decided to play ball rather then watch on the sidelines.

I needed to ask a vaste group of people what interesting things/sites there are in The San Francisco,Ca area. I'm from the east coast of Canada. Leaving mid December, 4 days after the possible WebBot prediction that has been keeping alot of debates heated and nerves very sharp. I'm not going to stop a business trip for it as I beleive we are all in the right place at the right time for whatever purpose. Just curious on what to check out that would follow the lines of what we all research.

Thanks in advance for your comments.
