This is a well-known hotel In Mineral Wells, Texas, which was once abandoned and borderline creepy. It's considered to be one of the most haunted places in the state.
For as long as many of us can remember, it's been red, yellow, green. Granted, in some places, you see a separate part of the light that shows protected greens or yellow or whatever. But generally, the 3-color combo is what we've known.
Now, whether some people in the Dallas and Tyler, Texas area actually understand what those colors MEAN is another conversation entirely. Yeah, we're looking at you, yellow light speeder-uppers! (That's a technical term, of course.)
No, it is not because the aliens that are planning to take over our planet will be jamming up the systems so there's no way we can call for help when they arrive during the solar eclipse. (Well, at least we've not officially heard that being confirmed. Yes, I'm kidding for Pete's sake.)
Besides, if aliens were going to be invading our entire planet, who on earth would we call for help anyway?
One thing you can usually count on is that you can avoid the gulf creatures of Texas simply by staying on land, but what if they follow you out of the water, and onto land too?
