Beginning in the early twentieth century, companies connected with drainage projects sold land to individuals for small truck farms. (A truck farm produces fruit and vegetables, which are trucked to city groceries.)
Much of the land was un-surveyed wetlands, which gave Florida realtors the reputation of selling "land by the gallon." Most purchasers never saw their land, but many others made a go of it. Everglades farming proved more difficult than anticipated, and few made a living as small farmers.
