for me to find a shed

. I walked around for 3 more hours today and all I found was an old Indian arrowhead (which is pretty cool to find, but when your in the heart of the great plains they show up pretty often.) I found over a hundred rubs, atleast thats when I stopped counting. But not a single antler. Maybe Im just doing something wrong, but I feel I have gone through some places with a fine-toothed comb and still came up empty handed.
It just frustrates the heck outta me[:@]
