Guerrilla group Swing Bomb SF installed dozens of swings on city streets and in parks this past weekend, just in time for some high winds to enjoy the fun. There's a "Swing Bomb SF" happening all over San Francisco as a guerilla organization installed 50 swings from trees and structures around the city. The swing locations are largely a mystery, though following the group on Instagram is a good way to track down where some of them are. Many are in parks, but some are in dense urban areas in the middle of the city.
