Opportunities

Funny.

On a recent morning, a 27-year-old skateboarder who goes by the name Josh Peacock peered into a swimming pool in Fresno, Calif., emptied by his own hands — and the foreclosure crisis — and flashed a smile as wide as a half-pipe. “We have more pools than we know what to do with,” said Mr. Peacock, who lives in Fresno, the Central Valley city where thousands of homes, many with pools behind them, are in foreclosure. “I can’t even keep track of them all anymore.” Across the nation, the ultimate symbol of suburban success has become one more reminder of the economic meltdown, with builders going under, pools going to seed and skaters finding a surplus of deserted pools in which to perfect their acrobatic aerials.
