Grassrivers
Real-world referencethe Everglades
South and west of Vice City the land turns to water. Grassrivers is the wetland of Leonida: saw grass, channels, stands of trees and very few roads. The real-world reference is the Everglades.
Airboats appear here in trailer footage. That is the clearest sign so far that the area is meant to be crossed by water rather than driven through.
The channels are the least certain lines on the community map. Water is hard to map from footage, and Grassrivers is mostly water.
How far south the wetland reaches before it becomes the Keys is not marked.
