America’s smallest post office is in a tiny 56-square-foot building in Ochopee, Florida, population 11. Its lone mail carrier drives 132 miles a day to serve 950 residents along the route. There’s enough parking at the tiny post office for your RV, should you stop by. It’s located along U.S. 41 at mile marker 71.9 along Alligator Alley, which connects Naples with Miami and passes through the Everglades. The building is not official post office design: it once served as a pipe shed for a tomato farm. But when the local general store burned down in 1953 it was converted to the town’s post office. Stop by during business hours to buy a stamp, mail a letter or visit with the postmaster. Buy a “Smallest Post Office” postcard, too.
