With most sketchy motels, it’s all about location. You can have a seedy looking place, but if it’s in the middle of a very upper class neighborhood, then it’s not so much sketch as it is a secret meeting place for old Country Club men to blow each other. (Obviously location is followed by the all important “am I shanked” variable)
With that, I present to you the Motel Inn in Terrell, Texas. (I did a lot of zooming / that’s closest I could see to a current working name)

At first glance, this motel embodies everything about sketchy motels. It somehow looks like how depression feels. And not normal depression. This is more like when depression pushes you to smoking meth out of a light bulb in a Waffle House. But, I want to zoom out, so you have an idea of how desolate the area is.

If it wasn’t for the cars in the parking lot, I’m pretty sure you could use this as the set for The Walking Dead spinoff in Texas. There is nothing around this place. But wait until you see what’s nextdoor to the right.

OK, not too sure what that is. Maybe a liquor store named Dreamers? Hmm, let’s go a little more to the right for some more clues.

An old gas station? Hmm. Wait, what the fuck? Does that say XXX on it?

If you said “1950’s gas station turned into a porn shop”, then you’ve won!
Yes, both buildings next door to this palace of sketch are porn shops. IN THE MIDDLE OF NOWHERE. I want to stress that. IN THE MIDDLE OF NOWHERE. That means that this motel is used almost exclusively by men in their 50’s who give a little nudge nudge to one another in the barely legal Asian section and then go play mouth fireman nextdoor with their “business partner”. The front desk person doesn’t care as long as they play nice. I have never been more sure of a place having a glory hole as I am right now.
Tune in tomorrow for more sketchy motels and remember that the submit and ask functions are open for your questions/submissions/anonymous blowjays in the Motel Inn glory hole.
