Wow.. You have to check this out.  There was a horrible accident on a family type Water Ride in Gold Coast Austrailia.  4 People were killed..2 women ages 42 and 32 I think, also two men, 38, and 35,.  This is what happened...2 people were ejected from the raft and the other 2 were trapped inside..they all died.  The park was shut down.  The thing that makes it wierd is that the water feature is like a tame family type ride..Definately things families would go on together. Makes you think Right?
