Ochopee Post Office in the Everglades is the smallest in the United States. The building, 8 feet 4 inches deep and about 7 feet wide, once was a shed to store tools and tomatoes. Now it's a full-fledged post office with room for only a single clerk. It has 40 P.O. boxes and sends a carrier out six days a week on a 170-mile route to serve 300 patrons who dwell mostly in the middle of nowhere.
You'll find the post office about 65 miles west of Miami or 35 miles east of Naples on U.S. 41, also known as the Tamiami Trail. Be alert, the tiny post office is easy to miss.
