Wow. There are so many things wrong with this post.
Just because there's no gate and no church
doesn't mean it's okay to dig holes in a cemetery.
Just because you
assume nobody cares about the cemetery
doesn't mean it's okay to dig holes there.
Just because your family
almost bought a cave or an area near it
doesn't make it okay to dig holes in a cemetery.
Just because it's a public cemetery
doesen't make it okay to dig holes there.
It's not okay to dig holes in a cemetery, period! There are people buried there, in the ground, where you think it's perfectly fine to dig. This alone should be enough to keep you away. You
will give a bad name to people who metal detect if you're caught there digging holes. The people on this forum metal detect, and we want to keep doing it. You need to read the posts on this site very carefully. You will not find anyone who supports digging up a cemetery.
What don't you understand about this??
