What is the furthest spot that an alligator has ever been found from its natural habitat?

Question

With likable causes being something like hurricanes, floods,etc.

Answer 1

the most likable causes are people
people used to raise alligators in their apartment in NEW YORK
people used to dump the alligator in the sewer when it got too big, thus creating the legend of giant alligators in sewage lines
it is also ILLEGAL to own an alligator in New York too and yet people are still doing it

Answer 2

Probably in a city or town, seeing as they are not "natural habitats" for the alligator, and any other place could be considered as such.
