The mountain town of Capulalpam in Oaxaca&rsquos Sierra Juárez is the sort of place forever doomed to being described as &lsquosleepy&rsquo. But when I got there, it seemed to have just woken up, if somewhat reluctantly. In the town square set amid steep roads and a view that trailed off into mist, stalls run by housewives offered tostadas and quesadillas with unpractised charm. Indigenous Americans had trekked in with wooden toys and handicrafts to sell.
