For me it depends on where I'm at. Most of the time I leave them where they drop but if I am doing pest control for a landowner I put them on trails or other routes I think they use, as sort of a deterrent - but it doesnt seem to matter. I havent been out all year but sometimes I give them to this dude who wants them to practice taxidermy or something but he only wants them if they dont have any skull or large damage, I'm like 'dude, I'm not thinking about whats best for you when I am shooting at them'! I dont know for sure what he does with them - dont really know if I want to know either! For all I know he does voodoo rituals with them, from the looks of him it wouldnt surprise me!
