It was a rainy day when it all happened. We were over riding at my friends house. I was on my dirt bike. We had made it about four miles in the woods, and then my bikes engine blew up. I was at the back of a group of five others, and they never noticed me not there. I was pretty irritated because I had never been on those trails and didn’t know where I was at. So I had too wait ten minutes till they stopped and turned around and found me. By this time I was very frustrated, so I was somewhat relieved when my friend Preston told me to hop on the back of his four wheeler. It was really muddy outside that day so everyone was trying to spray each other doing burnouts, and so was Preston. We had already sprayed my other friends a couple of times and we were having a good time. Well we parked in front of my other friends that are twins with dirt bikes. We all sat and talked a little bit while letting our bikes cool down. After talking for what seemed like an hour we started up all our bikes, and obviously me and Preston wanted to spray our other friends. So we put the four wheeler in first gear, grabbed the front brake, and mashed the thumb throttle. We were spraying them for like fifteen seconds and I wasn’t really holding on and then without any warning Preston dropped the front brake. I was terrified, I was sliding off the back of the four wheeler with two dirt chasing us not so slowly. And then it happened, I fell off looking at two bikes coming right at me. Then I woke up in a cold sweat at my friends house. I was spending the night with all my friends to go riding the next day.
