This is a cool thread.....lets keep this going.
Mine isn't really something I FOUND, but still creepy....I was 12 or 13 at the time (MANY years ago), riding my dirtbike with a friend of mine on an old railroad bed. Easiest way to start this is describe the layout. The railroad bed was a near perfectly groomed trail the went for miles....wide enough for a dirtbike or 4 wheeler, but overgrown enough that a truck or jeep would not fit through a good section of the trail. A good 10-15 miles from where I would access this road, there is a tunnel. I would say the tunnel was a good 25 feet high, about the same wide...somehwere around a 1/2 mile long, with a slight curve.... the curve is enough so that looking from one end of the tunnel, you can't see the exit. So, although it is not PITCH dark in the tunnel, you can only make out enough to orient yourself toward the center of the tunnel....my friend and I had been through the tunnel many times with flashlights and found the center (about 10 feet across) to be well groomed, perfect for the bikes.
This tunnel had been rumored at my high school to be a hangout for teens....drinking, smoking, etc. My friend and I, when exploring the cave earlier, found a lot of weird and creepy grafitti....lots of pentograms, swastika (not sure how to spell that), and devil type stuff. Regardless, we never found signs of anything too strange out there before....just beer bottles and empty cases (actually, I remember seeing a pair of girls panties by a fire pit now that I remember
So, this particular saturday morning we roll up and there is a smoldering fire at the mouth of the tunnel. My friend and I stop and take a look and listen. Don't hear anything, don't see anyone around....nothing out of the ordinary...both of us assume between the time of day and the look of the dying fire, no one is still around. We proceed slowly through the tunnel (both have dirtbikes, so no headlight), exit the other side and continue tearing ***. Not far from the tunnel exit (about a mile) is where people access the railroad bed by car. We notice an older Escort parked there....still, nothing out of the ordinary because people hunt and fish around there. On our way back, we round the bend to where this car is parked and notice a police car. Being the scared and ignorant kids, we turn around and haul it home a different way.
Monday morning my parents show me the front page news that a HS senior was missing since friday evening.....and found dead IN THE TUNNEL saturday evening....supposedly ruled a suicide. So, do the math....my friend and I evidently had ridden RIGHT BY the body at some point in the tunnel!!!! My parents later call the police and let them know that myself and my friend had ridden through there at some point in the morning....we were asked to come into the police station and tell them what we saw, etc. In a nutshell, bunch of kids that were known to be "Skinheads" were out there friday night, getting loaded. Supposedly the teen decided to stay behind and sleep in his car early saturday morning. Parents reported kid missing around noon on saturday, friends tell them where they were, cops find car, etc.
So that's my story....has kinda creeped me out for years, although I never SAW anything!
