I have found 5 sheds so far this year from the cab of my truck. That is four more than I have found in about 12 hours of ground pounding. Every year I find a lot of sheds by driving 10 mph past hay fields. If I see something that looks like an antler, I glass it. If it is an antler I ask the landowner if I can look for antlers in their field. Most people will let you pick them up, some won't. Most farmers in my neighborhood are glad for you to pick them up though. An antler can ruin expensive tractor tires.
