Anyways, I came across a cemetery set back away from the road in the middle of a corn field. It's March, so of course the corn had been cut. Once the corn grows over a couple of feet, the graveyard will disappear from the road.
The majority of markers were toppled and/or broken. The ones I could read were all from the 1920's or earlier.
Nothing is permanent. Even markers. Don't let the permanent marker people lie to you.
