Grand Bayou is, quite simply, an anomaly. Some people don't even believe it exists upon learning about it for the first time.
It's an isolated community in Plaquemines Parish, located along the banks of the Grand Bayou. If one were to travel there, he or she would take Highway 23 to a small road paved with oyster shells, follow that for nearly a mile and then continue by boat a short distance to the community, where they would find a number of homes and shrimp boats, but no streets.
You read correctly. There are no streets, no automobiles, no traffic in Grand Bayou.
In fact, a trip to school means waiting outside for the "school boat" — a bright yellow boat provided by a member of the community — to pick up the children and take them to the shell road to catch the actual school bus.
