When you die, your survivors call the funeral director and he provides the services you stipulated. Consider buying a burial site in advance only if you are confident that you will live out your years where you now reside. If your funeral director can't arrange such a trust, your bank probably can. But check first to see if your state is one of the 35 that have laws governing methods of funeral and burial prepayments. I asked our local memorial society.
Funeral directors cooperate in similar fashion.
If in a rational and mature way you can bring yourself to think about this part of life we call dying, and can go ahead and make the ultimately necessary arrangements, I think you will feel a real sense of relief and not a little pride. Another useful source of information is the National Funeral Directors Association's series of seven free pamphlets. 135 West Wells St., Milwaukee, WI 53202.
