Tell my story. 
With more folks choosing cremation, it becomes important to use memory stones or stones with your information showing your family connections. These can fit into family plots very easily.
For those with no family plots, it would be very nice if there could be some alternative offered at cemeteries. Any ideas?
Good question. I’ve seen memory stones at some of the cemeteries around here. Example: A man donated his body to science; the family installed a stone with the deceased’s birth and death dates, and a comment about the donation to science. Don’t know how practical that is for everyone.
I’m going to science after my death, too. I’ve left directions to scatter whatever cremains remaining in a garden or at a tree farm.
