High ground next to water. If worked ground all the better but not necessary. Walk all gullies in these fields. As above after rain they have a shiny glassy look. You can find one anywhere, but rocks of about the same size as arrow heads on top of ground is a plus, rocks wash up in similar sizes. Any flint shards also great sign. Stop and smell the roses, many times I’ve found them just standing still. Spotted them from tractor cab as well. Primary colors are black, red, grey. But not always! Jet black is mostly around here, nothing in fields look like that but black trash bags. You’ll find more going slow than fast. Find a place with flint shards and pieces, walk slow. I’ve found more than couple while taking a whiz. Here are some broken, crude finds which is what’s mostly out there.
