Several people, mostly kids have been killed near Ft Bragg over the years.
Some poking about in obvious areas to be avoided.
Others in long forgotten ranges that were planted over and forgotten years ago.
The area we set off the explosive had been a machinegun/small arms range for years and years.
People had walked over it, mowed it, whatever.
One stray bullet and a chance angle struck something long buried and it exploded.
Recently a fool cutting into a found Civil war projectile blew himself up.
I know this stuff is just toys in the attic to enthisiasts. If you ever saw the results of an accidental or intentional incident, you might feel differently.
I encountered undamaged hulks in a few places on Ft Bragg in the 60s, but I had sense enough to leave the earth undisturbed.
I also used those target ranges for various ordnance. Lots of Shermans, APCs and other stuff reduced to bits over the years. We mostly used live rounds. Finding one practice hull means one was used once.
Leave an ID in one shoe. Usually that much will be left.
