Its really too bad that rock fell. I am actually surpised that its never happened before.
Also, is there something up with Thunder Mountain? If I am not mistaken, the last big accident involving guests in the park was Thunder Mountain at DL. Whats up with that??
This is in response to the person some posts above that claims that we should get rid of the earthquake scene altogether. I felt that the MK's version paled in comparison to Disneyland's, due to the fact that the earthquake scene really adds to the chaotic nature of the ride. We get rid of that, we are further taking away from the overall "magic" of the parks. Keep it, but figure out how to stop the rocks from falling on guests.
