San Francisco has many events to expand your horizons and here are some of them that I have attended either as a participant or just to take the photos.
Just about every week there is a great Charity Event. My favorites are the Red Hot Ball put on by the b.a.y Fund to help under priveleged kids get to college. Then there is the Hands On San Francisco Masquerade Ball and the Volunteer Day. I help out at many of these buy either taking photographs or just hearding my flock in their direction.
In addition there are endless Happy Hours arranged. One I arrange called the SFSKI.com Avant Ski Happy Hour.
Burning man happens every year and its a great opportunity to experience something hot and dusty and different ... and a great place to take photos.
