The guerrilla sport of "urban golf"—in which players whack a ball at improvised targets on city streets—came out of the shadows for the first-ever World Urban Golf Day in late September, attracting hundreds of players in more than 40 cities worldwide. In Newcastle, Australia, both halves of an 18-"hole" course ended at pubs. In Portland, Oregon, about 75 players clad in garish retro golf-wear dodged trucks on a rugged industrial-zone course (they also visited five bars). Golfers in Caldas da Rainha, Portugal, plotted a course through the city’s medieval historic district. "Players love breaking all the elitist concepts of [the sport]," says a Portuguese organizer, Rita Groba. "And believe me, the city environment is a challenge."
