Seeing garbage left in the woods by hunters ( cigarette packs, bottles, cups)
QUADS on state land where it is illegal to ride them.
Also.....I use the two way radios when hunting, Pro-line. I have found this was a nice way to put my son in a tree stand and go to mine, but still be able to speak to him like he was sitting next to me. And if we wanted to get out and walk to me, I could lead him along with the radio. So in some cases, they do have a place for hunting.
