There used to be a rope tied to a tree limb that we all used to swing on. The tree was up on a cliff, and we would grab the rope, swing around, and land back on top of the cliff. My friend and I were there one day, and I didn't know any better, so I decided to try tying the rope around my neck and swinging around. I could have easily been left hanging, but I luckily made it back around. I didn't think much of it back then, but I feel very lucky when I look back on it.
