I believe some Native Americans (possibly on the Plains where wood would have been scarce?) practiced sky burial, where the body would have been placed on a platform and left for the vultures. I would prefer this but I'm not sure it's
legal any more and if it were, it would probably only for tribal members. I don't like bugs or their children, would
prefer not to kill a tree (or encourage cracking for gas) for cremation, and do have a fondness for those underappreciated sanitation workers of the bird kingdom, so I am sorry my heirs will probably have to choose a more mundane method of disposing of my remains.
Cheerfully planning for the future, eh? 😀
