We have found quite a bit of artifacts in our fields after we plow. All of the land is surrounded by a creek that flows into the Alabama river.
We have one field we call the arra head field. Very little clay mostly sandy dirt. We have found some flat and perfectly round rocks in this field also.
Whenever we plow we have the wives and my hunting buddys kids there looking over the fields to see what we can find. Its a lot of fun.
