Yunt,the same thing happened to me on my first pumpkin run, carb fell out, pitch dark and had no clue whatsoever. Luckily the group i rode with would always slow and pull to the side just to make sure we had everyone. Had to be pulled 11miles by an Arctic Cat
The thing was that my brother in law was right behind me with a rope so I told my brother to catch my other brother but he never showed up either. As we were going back to get my quad we finally saw my brother in law coming out. About an hour or so later. Still don't know what happened to him.
