I am curious about this and I KNOW someone on the disboards knows the answer. Are the rafts to Tom Sawyer Island on a rail or are they free moving?? I am asking because last time we were there, the boat was overloaded down and water started coming over the edge and getting our feet wet! The driver didn't seem very concerned that the boat platform was dipping into the water. Can these capsize? I know the paddlewheeler is on a rail, which means the rail lines would have to intersect at some point under water. Have there been any raft accidents?? Thanks! This board rocks!
