The USDA estimates that more than 2 million people live in rural food deserts, or low-income communities more than 10 miles from a grocery store. Four years ago, the last grocery store in Pilot Grove, Mo., closed its doors, turning the town into a rural food desert. The town had only a convenience store from which to bu food. That is, until 23 community investors came together to open Tyler's Market, a fully-stocked grocery store. On the market's first day open, Pilot Grove residents gathered at the store.
