My Granddad was a master carpenter, and walnut trees were his favorite live tree and walnut wood was his favorite wood to use his skills with.
He used to joke about buying a section of land for burial for he and his family and their families with their favorite tree planted over them.
Only a few of us thought that he was wrong.
Of course he wanted walnut tree planted over him. The only problem was his wife wanted a pecan tree over her grave site. So they would be buried apart, not how they spent their adult lives.
They loved children and family. They joked talked about
having a park with playgrounds, lakes/ a ballfield, streams in the area, and picnics areas (they loved family picnics.
Unfortunately, he died before before he got to start/implement his plan.
My ex-wife came up with what I thought was a marvelous idea: when you die you get cremated, but not at top temp, so there is more ash; the ash is then mixed with plaster of paris and made into a sculpture which can be made intoa lamp or stauary in a graden, or even mix with concrete to make a concrete bench.
