For many San Franciscans, the best weekend of the year is here. Outside Lands, the city's premiere music festival, kicked off today in Golden Gate Park with a scattered cloud cover keeping the temps in check - until the sun came out mid-afternoon to bless the stages with slightly warmer temps than last year.

Trey Anastasio of Phish, Billy Strings and Sturgill Simpson were among the special guests to join the band over three nights of concert and amid a city-wide celebration.
