Ok I hit the back button and this got deleted last night, I'll try again.
This isn't scary for me, just something I happened to be apart of and kind of feel bad about what we did at the time and how long it went on, but I still get a good laugh when thinking about it.
I was 20 and stationed at Fort Riley Kansas in 1992. My buddy and I wanted to go rappeling but the tower is off limits for individual use, so we decided to go at night instead. The tower is out in the boonies a couple miles from the barracks you have to use the tank trails to get there(the gravel and dirt roads tracked vehicles use, but you can drive on them also).
We head out about 11pm in dark clothing, we park off the main trail up the road from the tower, down by this tiny lake used for zip line training. It's about a half mile up and then down to the tower, we get there and there's a car parked there, windows fogged, noises, movement and stereo on softly, sex is happening.
We're debating on wether to rappel or just calling it a night, when we decided to scare them. My buddy loops around through the trees to the big log tower, I stay put, so I can make a dash back to the car in case things go wrong. Well within a minute the driver hops out and gets in a porta potty that I'm standing behind. He left the car door open and the stereo is playing, so I slowly creep around the side of the porta potty and quietly close the clasp lock and put a small stick in it.
I creep back and head to the tower to tell my buddy and we crouch down in the corner of the tower peering through the logs to watch, we're about 10 feet away. After a couple of minutes it becomes appearant that the guy must be taking a crap. seriously, you're banging some chick and have to hop out and crap in a porta potty?
So we eventually get bored and I pick up a pine cone or something and toss it at the car, the girl flips out and starts screaming, the guy tells her to calm down and continues with his massive crap. I grab a fist sized rock and toss it at the porta potty, the guy just starts saying repeatedly "was that you, was that you" (that still makes me laugh so hard), the girl is shrieking by now and the guy finally starts telling her it was nothing and to relax, while still taking his crap.
We wait a little longer and my buddy decides to let out the blood curdling high pitched death scream. The porta potty shook, from the guy jumping up mid crap, the girl is hysterical and the guy is trying to get out of the porta potty and he can't. He's telling her to help him, but she won't get out of the car, there both yelling at each other in fear.
It wasn't a a very big stick I had put in the clasp, he just had to push, but I think he was afraid he would tip the thing over and get coated in crap and get really stuck with the door against the ground. They're both still freaking out, you can see her because the dome light is still on, since the driver side door is still open. He finally convinces her to get out the drivers side and help him. She crawls over to the driver side and as she finally starts getting out, my buddy lets out another scream, she lurches back in, slams the door and locks it. She's freaking out, crying and screaming, I'm surprised she didn't drive away and leave him(maybe she couldn't drive stick). The guy starts jiggling the door harder trying to get out, since he's on his own now.
He still yelling for her to help, she is just crying and screaming(yes I feel bad about it now, but it was very funny back then). We creep around to the trees about 5 feet from the passenger side and we wait for a minute, they're both still acting crazy, I tell my buddy, let's get out of here in case he's actually pissed and not scared and starts looking for us.
Instead my buddy lets out another scream, they both flip their shit, she's hysterical, he's screaming "get me out of here" over and over. The guy finally sits down and kicks the door open, the noise of the breaking door freaks her out even more. he stood up and sprints the couple of feet to the car, he starts trying to open the car door but it's locked, he's banging on the windows, but she's just a sobbing screaming mess and isn't any help.
He final tells her he's running out of there and is going to leave her there if she doesn't let him in. The door finally unlocks, he jumps in, starts the car, and backs up like 80 miles per hour, he's in fifth gear before you know it driving like a bat out of hell.
We doubled back to the car, change and pull up on to the main trail to see if he was pissed and gonna get his buddies and come back or if he was truly scared, waited about an hour and he never showed.
I've always wondered what they told people, was it ghosts, demons, some bigfoot like creature, satanists. At that time in Kansas everyone was scared to go certain places because of satanists and stumbling upon their sacrifices.
I know people will think this was horrible, but it was originally supposed to be just scare them and have them back up and leave. It changed when he entered the porta potty, that was supposed to be "I wonder how that stick got in the lock", be a little freaked out, then leave. Then he took too long and it went over the top.
