very few days this spring, another small wildfire breaks out in the Pinelands, a 1.1-million-acre tract in southern New Jersey that spans seven counties and is home to some 500,000 people. So far this year, firefighters have doused the flames before they caused any significant, or at least widespread, damage. One fire turned four mobile homes to ash. Another closed the Garden State Parkway for a few hours. But Jersey won't always be so lucky.
