Food doesn't get any more local than when you can plant, pick, cook, and eat it all within a space of about five feet. That's the exactly the situation that building manager Peter Malerba finds himself in. The longtime Brooklyn resident takes advantage of having open access to a vast rooftop by growing a variety of organic delights every summer. But like a good Brooklynite, Malerba isn't high and mighty abou it. "I like gardening, so I do it," he says bluntly. His partner Liz Turner, a third grade teacher, uses the garden as an educational tool, teaching kids what local and organic food means.
