I'm sure there are. It got dark and the skeeters got bad before I could do much searching. I'm gonna wait until he disks the field and go check again. The ground is almost like concrete in the fields right now.
Could be. There was an old school a few hundred yards away and it appears they just dug a hole and pushed it in, then proceeded to dump 100 years worth of trash on top of it. My detector never stopped singing the whole time I was in the area. I will get a little closer look tomorrow when I have more daylight.
