Jacksonville, Florida.
Got gators in Texas. While most are in the southeast part of the state, some live in the Nueces River around Cotulla. Sightings there of up to ten feet or a tad more are known.
Some kind soul liberated a small one in the Rio Grande below Presidio. It was around for several years and was about a four-footer, last I heard. Not seen for some years, now, though.
