I have only been hunting sheds for a few years, with little luck. I hear of guys finding like 100 antlers in a day, here that isn't the case. I have only found two antlers so far, one in a big open field, and the other in a plowed field. Fields are a good place to check, at least for me. I also like to check thicker brushy areas around deer trails where bucks travel because the low brush can knock the antlers off if they're ready to go. Good luck,
