that spends more than a million dollars a day in San Diego. Finally we ended with the mothball fleet, scores of cocooned and silent ships at ghostly anchorage. Walking beside the aircraft carrier Phil ippine Sea with Commander Duncan, the fleet's maintenance officer, I noticed a slender electrical cable running down into the wa ter beside the hull. Commander Duncan explained that the cable helps to protect the hull against corrosion. "Without protection," he said, waving toward the carrier, "a hull that size can lose hundreds of pounds of steel a year through corrosion. And the corrosion isn't always uni form-it attacks certain points in a hull and forms pits or craters that eventually could eat right through. "Basically, corrosion is an electrical and chemical process. We've found we can slow it down, or even eliminate it, simply by running a current to the hull of the ship through the water from what we call anodes-bars of lead, graphite, platinum, or other metals that in a sense do the deteriorating in place of the Hardy campers line Pasadena streets on New Year's Eve. Their reward for the chilly, night long vigil: a close-up view of the resplendent Tournament of Roses Parade. A million and a half spectators jammed the route to watch the procession last January 1; more than a hundred million saw it on television. 612 hull, only at a much slower rate." He smiled. "That way, if the Navy ever needs these ships in a hurry, we can get them to sea ready for a fight without having to patch them up like old inner tubes."

The pos sibilities are broad, for the city has one of the world's finest zoos (page 623), some of the best fishing and surfing beach in California, and a brand-new waterfront recreation area, Mission Bay Park, that draws yachtsmen and vacationers from as far away as the Atlantic coast. In addition, of course, there is San Diego's colorful next-door neighbor, the Mex ican border town of Tijuana. Tijuana, with its bull ring, its jai alai matches, and its slightly faded air of endless fiesta, lures Californians across the border by the scores of thousands each weekend and returns them, as a rule, happier and slightly poorer. On weekdays the human tide reverses itself, as thousands of Mexicans cross the Blaze of blossoms on Burbank's float honors Walt Disney, 1966 grand marshal. Floral music staff and artist's palette resting on an open book represent "the three important elements in the Disney legend: story, music, and art." The float uses 5,000 orchids, 75,000 chrysanthemums, 1,000 roses, and 50 potted azaleas.
