So I haven't begun my adventures in MD'ing yet, but I've read a lot. Etiquette, do's and don'ts many common sense. I understand the disrespect MD'ing a graveyard and wouldn't detect where the actual graves are, but my town has a unique graveyard. There are two churches that sit on top of a hill, however during the Civil War only one existed. The graveyard that is there now was either very small or non-existent then. At that time, Union artillery took up position at the graveyard, in the unused portion of it, of course. The church was used as a hospital. Across the river in the bordering state, Confederate artillery set up their position, and, of course, a battle ensued. The church was bombarded as well as the cemetery and the land around it. Fast forward to today's time, the graveyard is bigger, but there is a portion that is still unused. A friend sought and received permission to detect the unused portion of the cemetery. Still disrespectful, despite receiving permission?
