If you hunt in and out of xtreme thickets there is no way to find your way in the dark without a marker Ive tried numerous times and its terrible, where and how I hunt needs to be marked. The tack type are all over public land and should be removed, yes I agree with that. There is a great alternative though, I use the twist tie ones that go around small limbs. You can mark out your trail, hunt your spot and take them as you leave and reuse them on your next hunt. If you leave them there and there gone the next time you come back, thats your fault and never leave a stand up on public land. And remember this, there are many animal rights/anti hunting activists in our woods and parks that will do all they can to destroy hunting gear, I saw it happen, so dont be so quik to blame a fellow hunter if anything is missing.
