Traveling on Highway 41 in southern Florida, if you don’t blink, you’ll see the smallest post office in the United States. The 7- by 8-foot building, formerly a storage shed for irrigation equipment to water tomato plants, now houses a fully functioning post office.
The shed was pressed into service after a fire in 1952 destroyed the Ochopee general store, which previously had housed the post office. The post office is in Big Cypress National Preserve.
The building is small, but the Ochopee mail route is large, covering three counties and is about 132 miles long, according to Roadside America.
