Hint to the funsters who want to end the gorg day with tunes: If you’re round the Golden Gate Bridge, check out the Tunnel Show of the Marin Headlands, which started at 3 p.m. today, Feb. 18.
Inside an old army barracks tunnel, there will be performances by Living Breathing Music, Hector Zapana, Ship Snowblink, Okay, and a classical Indian ensemble organized by Charles Lloyd.
