For no particular reason, here are two little Florida Everglades airports:
Marco Island - KMKY
Dade-Collier Training and Transition Airport - KTNT - interesting as when construction started, in 1968, it was planned as the biggest airport in the world, with 6 runways, named the Everglades Jetport. When the environmental damage that it would wreak had been appreciated, the idea was abandoned, and the airport is only used for training these days.
