Plan to try it
We had a demonstration of grave dowsing at our Coffey Cousins' Convention in Nashville the last week in April ["Dowsing for the Dead -- Genealogist searches out of respect for sacrifices of the pioneers" (http://www.mc cookgazette.com/story/1097368.html)].
It was and is very fascinating. My husband and I have made a set of rods and plan to try our luck on Wednesday while decorating our family graves.
I sincerely enjoyed your write up on this subject.
