By age 62, Dave Sargent tired of being the dairy farmer he'd been for most of his life.
So he quit, and planted a small garden -- a third of an acre -- with yellow squash, zucchini, eggplant and blackberries. Once the vegetables came in, he went to his local Wal-Mart to ask if the store was interested in buying his produce. The manager agreed.
A decade later, he's now selling $1.5 million worth of produce each year to dozens of Wal-Mart stores across the country. He now has 1,400 acres, and has expanded into growing cucumbers, green beans, wheat and soybeans. His business got so big that he took on a partner. In the summer, the farm employs about 40 workers.
"I owe all of my success to Wal-Mart," he said. "Without it, I would be nowhere."
