stARTup Art Fair
One of the cooler art events in the city (though that’s something of a tallest pygmy contest with the dearth of art culture in SF), the fair is now in its third year at Hotel Del Sol on Webster St. in the Marina. Over 50 artists participate in the take-over of individual rooms and the courtyard pool area of the hotel, with artists conversations and a seminar on women in art. 4/28-30, Fri 7-10pm, Sat noon-9pm, Sun noon-7pm.

King’s Day Celebration
There’s a Dutch community in San Francisco, apparently. Because each year at this time they gather round the Murphy Windmill in Golden Gate Park to celebrate King’s Day, the biggest event of the year for Nederlanders. Flea market, music, beer garden, food trucks, kid’s games are all part of the fun, as well as typically nice weather this time of year. 4/29, Saturday, noon-5pm.

Dancing in the Park
The 10-day event that is Bay Area Dance Week culminates this weekend with various workshops and free performances. Dancing in the Park is one of the highlights, with some 30 top Bay Area dance troupes and schools performing in the band shell next to the de Young Museum. 4/29, Saturday, noon-4:30pm.

Caesar Chavez Day Parade
The largest event honoring the late labor and rights activist, the parade begins at 11am and makes its way from Dolores Park and ends at a street fair at 24th between Treat Ave. and Bryant St., which features a car show and plenty of food. 4/29, Saturday, 11am-6pm.

“Summer of Love” Block Party
It’s been 50 years since San Francisco became famous for hippies, tie-dye and psychedelic drugs during its famous summer of love in 1967. The festivities for what promises to be a summer of events kick off with a block party on Telegraph Ave. in Berkeley with free concerts from 60s cover bands, food, crafts and kid’s games. 4/29, Saturday, noon-5pm.
