LOST IN THE SUPERMARKET

Like birds, whales, and my fellow gringos, I fly south for a dose of vitamin D in winter, down to San José del Cabo, the geological tip of California and the finish line of Baja desert racing. I’m not usually a big-box shopper, but stocking up for a week’s worth of supplies means hitting Mega, the retail chain that sells everything,” and the largest producer, with about 400,000 units sold last year.
