SAN FRANCISCO GOOGLE CALENDAR

Dear Internet Santa,

What I would like is a Google Calendar I can subscribe to that will tell me all the public crap going on in San Francisco. There are too many specialized calendars in you right now to bother with, and this is broken and slow. The calendar I would like should tell me about things like

- Public protests
- Marathons and other sporting events that take place in the actual city
- Gay Pride weekend and other festivals

so that I can either plan around them or go to them. I just want one calendar that does this, I do not have the patience or desire to subscribe to fifty different ones to get an aggregate interference pattern that produces the desired results. Internet Santa, hear this wish and grant it with all available speed.
