Update: The turf soccer fields at Fulton Street have been extended for fall.
Original: Open every day from morning until 9pm, through summer, the two modular turf fields on Fulton Street (between the Asian Art Museum and the Main Branch of the San Francisco Pubic Library) are the new spot to play soccer! Presented by San Francisco Recreation & Parks Department with Street Soccer USA, and additional programming with America Scores.
The inclusive schedule for all features free drop-in times, free league play times for both adults and youth, and more on the option to rent the field for group use. More info here.
