As a matter of fact they were, Rick.
After a lot of searching, we found a couple fields that produce every year, and a few more that do occasionally, but there's a lot of looking involved.
Most of what my Girlfriend and I find, are broken parts and pieces of different things, but we manage to find a few that are intact now and then.
A lot of people I've talked to about it, think It's wrong to take them, but I think each year when the plow goes through, more of them get broken.
We write down where each was found, county, town and as close to the exact location as we can, so they have some documentation. That way they have some archeological value, and they're not just a collection of artifacts that nobody has any idea where they came from.
I'll post some more when I have time. Thanks.
Bob
