This story is from my Mother, she told me this a few years ago.
When I was about 12, my family and I went out camping to a place about 3 hours from our home. I do not remember the name of the place, but I do remember what it looked like. To your left, you see a stream and then thick trees. Straight ahead, you see a bridge standing about 7 meters off the ground, 500 meters away. To your right, it is more trees and then a small road we took here. This bridge was abandoned, nobody came here.
We set up our tents and began making the campfire. There was me, my parents, my 3 sisters and 3 brothers. About 4 tents in total, if I recall. The first day went okay. All that really happened was me feeling like I was being watched constantly, by something in the forest. I shrugged it off as no one would believe me.
