Saw the Dead play many times, free concerts in Golden Gate park, shows at the Avalon Ballroom.
Fave, however, was when the Dead jammed at the Family Dog, a small music theater at the north end of the SF beach Playland arcade, that's the top of the Dog to the left in the background.
On warm summer afternoons the Dead would have all the exterior doors opened up to let in the ocean air and then jam for hours while we surfed right across the road, hooting to hot riffs between riding waves.
Words don't adequately express just how magic the SF music scene was during the 60's, and city surfers were smack dab in the middle of it, the sounds propelling us along like we had rockets tied to our ass..
