The desert, of course, has always been a place for visionaries, and where Wright lorded over his imperial kibbutz, others followed, some to craft concrete dreams of utopia out of the desert scrub, others to stare into the abyss, hoping against hope that more than the abyss would stare back.
But if deserts are places where the spirit is purified by nature's beauty and stiffened by hardship, Scottsdale the city is somewhat more prosaic. Cheek by jowl with the state capital, Phoenix, it is a quiet, low-key kind of place, with a disproportionate number of hotels and more destination spas per head than anywhere else in the USA.
The Sanctuary on Camelback Mountain (00 1 480 948 2100; www.sanctuaryoncamelback.com; doubles from $259) is probably the most indulgent place to stay, with spectacular views over Paradise Valley and casitas with outdoor hot tubs and wood-burning fireplaces.
Scottsdale is often ranked as one of the most livable US cities, and indeed, when driving out of town, passing the gated entrances of private houses, it does seem like a muted version of Beverly Hills. At high noon, the streets downtown are somnolent and almost eerily clean: I wasn't surprised to read of a local golf tournament called the 'Waste Management Phoenix Open'.
