There is usually some event happening every weekend in the city. For example, every neighborhood typically will have their street fair on a weekend so you could be going to many different street fairs that touch on that neighborhood's vibe or cultural background (like the North Beach one obviously associates with the Italian community). For something def more wilder if that is your bag, you could go to the Folsom Street Fair in your S/M garb and you won't feel out of place. Want to go buck naked? Go for it. Go check out our Gay Pride parade, which is one of the bigger ones I believe, if that is your thing. How about attending the Chinese New Years Parade that is arguably the largest one outside Asia?
You obviously are aware that SF is a major food town, probably #1 or #2 in the US, depending on who you believe. I believe, Bon Appetit ranked us first fairly recently. It is always New York or us. So, there are many cutting edge restaurants to check out here, from the uber expensive to the San Tungs of the world. I am too old for it, but I am sure a lot of the millennials will mention the bar scene like in the Mission and perhaps the dance clubs here. I have been to Ruby Skye in my day and it is a pretty good place for dancing if that is your thing.
How about the many music concerts that we have from Outside Lands to the free concerts at Stern Grove on some Sundays? How about the Hardly Strictly Bluegrass concerts that are FREE in Golden Gate Park?
Let's not forget the museum and art scene here. You have SF MOMA, which is a highly regarded museum, one of many. You have the De Young Museum, the Asian Art Museum, the wonderful interactive Exploratorium and Academy of Science that are wonderful educational places for adults and kids alike.
Let's not forget some of the more touristy things like visiting the Golden Gate Bridge, Coit Tower, riding the cable car, visiting one of the largest Chinatowns outside of Asia, and checking out say Alcatraz. You could come up here for the Blue Angels during Fleet Week and check out the naval vessels while catching the air show. The Beach Blanket Babylon show in North Beach has been running for years. Wonderful satire that plays on the current events.
If you are a big into exercise, you probably would want to come up for our many marathons happening on typically early Sunday mornings. Who doesn't love the Bay To Breakers race that cuts across the city and you have the zany costumes? You could do the Escape From Alcatraz triathlon if you are really an exercise freak.
Zany events like that one held on a Sunday where ADULTS join in and ride Big Wheels down what is the real most crookedest street in SF is always fun. The massive pillow fight in Justin Herman Plaza every year on Valentine's Day night (I believe) is always a kick to see. There's a day where everyone dresses like Santa Claus and hits the bars all over town.
If you are into pro sports, we obviously have the SF Giants and soon to be Golden Gate Warriors to fill up your day that way if you like.
Is that enough for you????
