Where did all the people go on South Padre Island?

We start out our day looking for people on the Island, we see no one

South Padre Island is the 2nd largest barrier island in the world, the largest being Long Island, most of the island is empty, it runs from Corpus Christi to Brownsville, hardly anyone here, and there are only 2 rv parks on the island

The Gulf side has miles of white sandy beaches, Conde Naste rates this the number 3rd best "wild beach" in the world, but we find no one there

It's 90 degrees out and the water is warm, no reason not to find someone here, it's a tropical paradise

The other side of the road is the bay, in season it looks like they have to separate these two, and charge them $3 to get on the beach, today, no charge, and no body there

We send the dogs out to find anyone, they look behind everything, but find no body

Schlitterbahn means slippery road, they are the people who invented water parks, this one has been rated the number 1 water park in the world by many sources, but it is closed, no one here

The whole water park is in a sandcastle form with the Shrimphaus restaurant that you float up to on your inner tubes, can you imagine? You have to, cause no one is here.

There is a Sea Turtle rescue center here on the island, so many of the sea turtles are caught up in the shrimp nets and die, but nobody is here either

Also a birding center is next door, over 500 different birds migrate to the Rio Grande Valley, and over 400 butterflies too, but not that many people

We finally run in to an endangered brown pelican, but still no people, but we find the visitor center open, with a woman in it on a Sunday morning, and ask her, "Where are all the people?" She says they are always slow in September, October and November, but the rest of the year is good, she explains that they only have two rv places so they don't see many of the snowbirds, but the ones who stay in the Rio Valley come up and spend the day, also, they like it slow now, gives them time to do repairs. I still don't get it, it is over 90 and humid, too hot for me, and it is miles from anywhere, just right for a Stephen King novel.......
