> Vernon gained infamy in the late 1950s and early 1960s due to the improbably high percentage of residents who made insurance claims for lost limbs, leading to an investigation of whether residents of the city were intentionally dismembering themselves for the insurance money. These insurance claims from Vernon, with a population of 500 to 800, accounted for as many as 2/3 of claims nationally, but there was no way of proving that any particular amputation was deliberate.[9] This led to Vernon being referred to as "nub city" during this period. In 1980, Errol Morris attempted to make a documentary about this phenomenon, but after being threatened by city residents and physically attacked by one, he changed the focus of the film, resulting in the 1981 documentary film Vernon, Florida.
