For one Vermont couple, "local" doesn't mean heading to the farmers market. It means finding a natural salad bar at your picnic spot — or maybe even in your backyard.

Nova Kim and Les Hook live on a lush farm between a large lake and the Connecticut River near the Vermont-New Hampshire border.

In the 1970s he was doused with water at a science meeting for presenting his theory on sociobiology. Another new evolutionary theory he introduced a few years ago on kin selection continues to be hotly debated.
