In the interest of fairness, I would point out that one thing to consider is that by virtue of its population and proximity, Texas provides a large percentage of the visitors to Cozumel. You could ask any tourist you see there where they are from for whatever reason and there's a very good chance they will say that they are from Texas. That's especially true now because of the dearth of cruise ships and the reluctance felt by many to take long plane rides.
That said, there are people who live in Texas and there are Texans, and they are not always the same thing.
