Yep, and since cemeteries are off limits, stay out of any battle sites, any skirmish sites, any parks where someone has died, any yard where someone has died, any carwreck, any plane crash since these are just as sacred as a cemetery. I don't see a problem is you do it respectably and get permission. If you get permission to detect then detect. Stay away from graves and detect the vacant areas and the road and walk ways. O, I almost forgot to mention any boat that has sunk or any beach where someone has drowned or died.
