ATLANTA — As she does every evening, Kelly Callahan walked her dogs through her East Atlanta neighborhood. As in many communities in a city with the 16th-highest foreclosure rate in the nation, there were plenty of empty, bank-owned properties for sale.

She noticed something else. Those forlorn yards were peppered with overgrown gardens and big fruit trees, all bulging with the kind of bounty that comes from the high heat and afternoon thunderstorms that have defined Atlanta’s summer.

So she began picking. First, there was a load of figs, which she intends to make into jam for a cafe that feeds homeless people. Then, for herself, she got five pounds of tomatoes, two kinds of squash and — the real prize — a Sugar Baby watermelon.

“I don’t think of it as stealing,” she said. “These things were planted by a person who was going to harvest them. That person no longer has the ability to. It’s not like the bank people who sit in their offices are going to come out here and pick figs.”
