Barreling through California's Central Valley, his big rig's 48-foot refrigerated trailer loaded with lettuce, peppers and tomatoes, Brett Goodroad acknowledged that he's probably among the last generation of long-distance truckers.

With a master's degree in fine arts and a penchant for listening to classic books on the road, he doesn't fit the standard trucker profile. But the aptly named Goodroad, who has put in more than a decade driving for Veritable Vegetable, an organic produce distributor, is an eloquent spokesman for his millions of comrades now traveling America's highways.
