Where is the smallest post office in the United States?

Ochopee, Florida

This closet-sized, 7x8-foot building used to be an irrigation pipe shed for a tomato farm. It was pressed into service after a fire destroyed the Ochopee general store -- which also housed the post office -- in 1953. The town, which sits on the edge of the Everglades, and which reportedly has a population of 11, has been happy with it ever since.

Shannon Mitchell works in this tiny place as its clerk, and she says that she has the coolest job in the world. She has a phone, a computer, an air conditioner, a fluorescent tube for light, and a pair of tiny sliding screen doors to keep out the giant horseflies. Everything that she needs is obviously within reach. The job is quiet, as you might expect, although she does get occasional visits from people from all over the world who stop by to get something postmarked. Shannon has a stack of Ochopee Post Office post cards on the counter, pre-stamped both domestic and international, for when the tour buses pull up.

The towns of, Hell, Mi, Little Flock, AR, and Monkey's Eyebrow, Ky are real places.
