What lucky duckies we are to have Balboa Park for our backyard! And as a bonus (on a rotating schedule) several museums have no admission every Tuesday. This means today you can visit the Art Institute, Museum of Man, Friendship Garden, Mingei and or the Museum of Art for free! Thanks to ball bearings, the Timken Museum of Art is your gift — admission’s always free. Other deals…an International Organ Festival on Monday evenings at 7:30pm and Twilight in the Park concert series featuring live music has been delighting visitors for 27 years with programs ranging from military bands and Dixieland jazz to big band swing and Latin salsa on the stage of the majestic Spreckels Organ Pavilion. Tonight evening enjoy the United States Navy Band Southwest beginning at 6:15.
