Possible Scattering Of Human Remains On Disney Rides Reported
Ride Closed, Police Alerted After Woman Seen Dumping Substance On Ride

Disneyland workers were recently forced to close the "Pirates of the Caribbean" attraction after a ride security camera caught a woman apparently dumping human remains, in what may be a growing trend.

Workers at the Anaheim theme park spotted the woman sprinkling an unidentified substance into the water on the "Pirates" ride. Anaheim police were notified of the incident.

The woman told Disney park workers that the substance she dumped was baby powder, but officials are investigating the possibility that she sprinkled human ashes, Local 6 reported.

Some Disney watchers said park-goers tell them that people smuggling in the cremated remains of their loved ones and then sprinkling ashes on rides has been going on for a while.

They said it started at the Haunted Mansion, but now the "Pirates of the Caribbean" ride is growing in popularity.

Disney officials said they were unaware of any confirmed ash-scattering incidents in the park and didn't believe it to be a problem, the Los Angeles Times reported.

Park officials said there was no real way of knowing if cremated remains were dumped into the "Pirates" ride.
While I don't like the thought of people spreading ashes where ever they wish through out the parks, I do think that this is an area that Disney should address and get their arms around the issue. If Disney were to come out and acknowledge that there are many that wish to have their remains rest at Disney, they could then develope a respectful way for familys to fullfil the wishes of their loved ones. I have no idea of how this could be done and I am sure there are envoromental issues, but I am sure that this could be done in a very respectful way without having ashes spread in public areas. Disney has always met families needs with weddings, rehitching services, and even condones the organized gay days.

They could take this issue right now and make it a positive for both Disney and the families.
