Sitting on a foreign beach, I realised a truth. No matter where I go, my subconscious provides a template, and what it shows is a configuration of Poole Bay and its rituals, of day excursions from my childhood Southampton home to that expanse of yellow sand by the green-blue-grey English Channel, between Hengistbury Head and Swanage, pivoted on Bournemouth.
I am programmed to grade all beaches, liberty and licensing laws by that slice of Dorset and Hampshire. It is where I started, it is where I ended up recently.
Within that slice, the thin sliver of the Sandbanks peninsula was odd. I couldn't quite figure it when I was a child, it had a nice beach, just like Bournemouth proper. But it was slightly different. In hindsight, I realise it was mid-20th century genteel. There was money about in Bournemouth, but discreetly more in Sandbanks, a land of sun-loungers rather than my day-tripping family. Yet Sandbanks was part of Poole, and that town was never, well, chic.
By the time I next looked, in another century, Sandbanks had got itself billed the "Golden Riviera", the "Palm Beach of Britain". Property prices - thanks to a PR coup by a wily local estate agent - were being touted as the fourth highest in the world, higher than New York, Paris and Singapore (shed a few million on a little place in Panorama Road overlooking Poole Harbour) and a conga line of Hello! celebrities, led by Jamie Redknapp and his pop star wife Louise, were billed as residents. The harbour itself had become an aqua-megalopolis of yachts, sharky speed boats and cafe-bars mushing up "battered cod and green pea puree".
Country reopens at Studland on the other bank of the 79-year-old Sandbanks floating bridge service. The Bournemouth-Poole stretch is Audi TT territory, neat cliffs, plentiful foliage, big apartment blocks. There is a gradation. In the beach's border zone, Welcome To Bournemouth is accompanied by a Martin Parr-style blow-up picture postcard of beaches and pier, while Poole, remembering its manners, boasts pottery tiles of yachts leaping through the waves.
Kids were still in school so it wasn't crowded on the beaches that day. I walked towards Branksome Chine - one of Poole's six starred beaches. I knew where I was going, I had been there once before, when the wind was blowing a gale last spring and spray blurred into the drizzle.
In 1932 at Branksome Chine, in the spirit of that age, a solarium-cum-bathing spa was built. It had the look of a 30s roadhouse about it, the kind of place to fantasise about pulling up in a Hudson Terraplane and listening to Artie Shaw on the wireless. A period photograph does show a lot of big motors outside - but no Hudsons.
Post-war it became a cafe. But, against the odds, it did not get knocked down. It survived successive property booms incognito as a cafeteria. Then, about six years ago, new proprietors began negotiating with Poole's conservation officer about a revamp. Two years ago, it reopened as Branksome Beach, a restaurant, takeaway, cafe and bar.
The food is good, not cheap, not exorbitant and seasonally changing. There was, for example, sea bass at £14.95 and calve's liver and bacon at £12.95. It opens from 9.30am to late at night, working through breakfast, lunch, cream teas and that rarity, the cheese scone, and dinner. Most of all it enhances the 1930s features, and pulls in both trippers and loungers.
Some element of austerity had gone. The opening hours had done it, along with the cheese scone. The geography was unchanged, but the template had still slipped.
