hey just something to think about
we all know deer like minerals
and well many DOT depts use salt and salt like mineals and chemicals to spray roads in winter?
ever wonder what effect it has on deer that either lick them, or eat plants and like that get residual spray on them or out right eating the salt that spills into piles??
just a something to think about maybe!

a good way I always used on coyote, is to keep tabs on there poop?
if there eating a lot of deer you will see a lot of deer hair in it!
same as for other critters, but deer hair shows up a lot in what I find in many areas, so I know they live on a lot of deer1
