Nice finds. Our local wild population is not that great, its been low for a few years now.
I do manage to find one or two wild bucks antlers every year when I am out cutting firewood, but there is never enough of a carry over of bucks to make serious shed hunting worth it, been running the trail can since the first of the year, 2 spikes and a 3 point survived, that's it. I would love to find an area nearby that has a good wintering population, I do like to get out and walk in the winter and it would be nice to find more sheds. Congrats on your finds.
