The only thing really appealing about cremation is the possibility of having bits of my ashes spread in multiple places that matter to me.
There is, however, nothing whatsoever the least bit appealing about being buried in a sealed casket and burial vault. Return me to the world, even if you must reduce me pretty much to atoms first.
Feed me to tigers. Leave my carcass on a mountaintop for the vultures. Make Soylent Green and have a party. Cremate me as a last resort. But don't bury me unless you really need to show how much you hate me -- and if the feeling is mutual I'll come back to haunt you.
