Unfortunately for writer Jon Steinberg, the Healthy Highways guidebook wasn't yet available when he and his girlfriend drove from San Francisco to New York City last fall. "It definitely would have come in handy along those fast-food-only stretches of I-80," he says. The former editor at Diablo Magazine has written about travel, food, and health issues for Backpacker, Alternative Medicine, the Village Voice, and Timeout New York. He is currently an associate editor at Time Inc. Custom Publishing.
