I know this is a genealogy site but since this was already posted I believe it needs to be addressed. This law is completely unnecessary, all states have trespassing laws that the landowner may use to prosecute personnel who were not invited to be there. This law has nothing to do with the private landowners rights but simply another step in making it illegal for law-abiding people to collect artifacts. Most antiquity codes make an item over one hundred years old fall in this range. Soon you won't be able to keep your most treasured family items because you won't be able to prove where they came from. In Texas it is still legal to dig on private property with the landowners permission and I feel for the people of Georgia who have already lost another personal right. There are already laws in effect to protect federal, state, county and city property. Don't get me wrong people who trespass, dig up graves for strictly personal gain need to be addressed but this law will do nothing to keep them from trying. Remember a few bad apples does not ruin the whole barrel.
