Let them investigate! Tons of old nails, buried old fence wire, 100 years of accumulated junk, cast iron plumbing, broken plow points, private garbage dump(no longer used) over a 15 acre patch of land. That is a lot of investigating they will have to do!
Every geezer with a metal detector knows you check the hole after you dig something out.
