If you are going to a cemetery, even if you have the plot number, take a metal rod with you. Should you be able to find the general spot of the plot, but there isn't any stone, try gently prodding the ground in that area. My grandmother died in 1975. Two years ago, looking for her grave, knowing there was a stone, I could find nothing. My cousin went back a year ago. She took a metal rod with her, and since we knew exactly where the stone should be, she tried this. She found it in a few minutes. Dirt had gotten over the sides, and grass had grown over it to completely enclose it. In the same cemetery, my gr-grandparents are buried. The area they are in is totally grass, with one or two upright stones, here and there. The office told me to count from the other stones, because they are vary evenly laid out. I tried prodding with a pencil there, but now knowing that a grave from the 1970s was so covered, I know I will have to try something a little longer next time. Kathy
