One day my friend and I were in the woods. In the woods we were in was a creek. We followed the creek until it opened up into a larger creek which runs under the bridge to West City Park. Near the place where the small creek met the large creek, there was a vine that when you swang on it, it went about ten feet up into the air. When I swang on it, at the peak of its height, I let go but I tried to grab back onto it. I landed on my back and couldn't breath.
