Most of San Francisco’s Presidio will open to the public on Saturday, the National Park Service said after a right-wing group canceled plans for a rally at Crissy Field.

Officials at Golden Gate National Recreation Area said late Friday that the organizer of the Patriot Prayer rally had relinquished his permit. Concerns that the right-wing event would draw counterprotesters and become violent prompted the park service to draw up plans to limit access to much of the Presidio.
