Sometimes art-fair weeks have an echo-chamber reverb—the same canapés, the same Instagrams, the same Damien Hirst spin paintings. But if you’re lucky, the stars align and bequeath you unique experiences. On Friday, at 10:30, the morning after the opening of the Dallas Art Fair, which is the centerpiece of Dallas Art Week, Christie’s gave me the keys to a 2015 Bugatti Veyron 16.4 Grand Sport Vitesse—at 255 mph, the fastest car on the road, and at $2.5 million, just about the most expensive. At 11:30, I was in the home of Dallas collector Marguerite Steed Hoffman, watching as she delicately turned the pages of a medieval illuminated manuscript while standing next to one of Gerhard Richter’s candle paintings. And at 12:30, I ate a plate of fried alligator. Dallas made this all seem normal.
