The trouble with facelifts is that they need repeating. By 1978, the termites got into the woodwork, the letter O rolled down the hillside and, in a city where appearance is everything, the sign brought Angelenos more shame than fame.
So the neighbours got together and, led by luminaries such as Hugh Hefner, raised the money ($27,000 a letter) to restore the sign, helped by Andy Williams, Gene Autry and Alice Cooper.
Wherever you go in the eastern end of this city, the sign demands attention, even as it's being repainted yet again. In the midst of Griffith Park's 1600 empty hectares, the sign looms close up, drawing you to its summit setting. From there you look down on the much vaunted and vaulted Forest Lawn Cemetery, where the stars make their last appearances above ground.
Every morning of our month-long visit, we walked the trails under the sign in the company of Los Angeleons of every shape and colour. They are a mixed bag of walkers, offering either cautious good mornings or far-away stares.
But they're well dressed and equipped. The T-shirts carry defiant messages - "Let's do it", "All the way", "Everything is beautiful" and, most popular, "I ran to the Sign". Their shoes are sprung, colour-coded and elaborately laced, and the drinking equipment is hi-tech, piped, harnessed and big enough to irrigate a body for a Coast to Coast run.
Even the dogs carry water bottles. One overweight English bulldog carried a twin pannier of bottles. He looked exhausted. Unlike the energetic and very professional dog-walker we met every morning with 12 pooches in tow, held in check by a maze of leashes that she managed to keep untangled.
She sailed past with the greatest of ease, murmuring directions to her charges and leaving a whiff of perfume in her wake. No risk here of disobeying the conspicuous instruction: "Dog defecation must be removed immediately by owner under penalty of law."
The local government culture that rules this land is surprisingly officious for a laidback Californian city. "No trespassing", "no loitering" and warning notices abound. My favourite is "Beware of rattlesnakes and mountain lions". No mention of the whipsnakes, ringnecks and scorpions that also live here. Happily we avoided all these critters, apart from several coyotes slinking about like sly Alsatians with howls like a fire siren.
It's a strange experience for a New Zealander to walk these tracks under the sign. We ought to feel at home in this rural space, empty and silent except for the constant clatter of helicopters overhead, monitoring crime, weather, news, homeland security and freeway traffic.
You walk here not under the shadow but in the light of the Hollywood sign. It's more than a label - it's the promise of a dream that might one day come true, if only you could touch it.
But you can't, of course. The sign is visible everywhere but you can't get near it. High wire fences and a battery of warning notices protect the sign from starry-eyed tourists, vandals and terrorists. Look, but don't touch. Available only on celluloid and electronic image.
That's the Hollywood way.
