Bim & Nsb
Bimini has two great airports. The "North" airport is acutally for Chalk's Sea Planes, which no longer flies. They had a cement pad about 100x100 feet where the plane came up out of the water and turned around on. Baggage/ticketing/checkin/everything else was handled in a small building adjacent.
BIM is the south airport. Real runway and everything, but the same small house idea is used for everything, including customs/immigration.
