Eating locally harvested food whenever possible helps the farming economy and the environment. (Come December, those fresh blueberries have to travel by plane from Argentina to get to your breakfast table. Enough said.) To help you choose wisely, T+L found four regional fall standouts—and restaurants featuring them on their menus.
