I haven't had any pass, but when my friend's 16' burmese passed after 8 years, she skinned her. It took about a dozen 10 blades and bout 6 hours. I know it sounds morbid, but the skin makes a great display and she said it was a "letting go" experience.
I can definately see where she was coming from and I think that's what I will end up doing when the time comes. (of course that's not for another 30 years!)
When people ask me if i'm a cat person or a dog person I tell them, "I'm a snake person"!
