Thanks for the pictures Tana. Makes me home sick when I see those Fall shots of harvested corn and bean fields. I'll be back in Hoosierland for Christmas and digging holes in my dad's corn fields for a week.
If you have a GPS I'd mark all of my finds in a field that large. The fact that it's plowed will create strewn fields of relics or coins. Keeping track will help you map out the hot spots that you should concentrate on and maybe even grid.
