They need to make scent free signs. I could imagine trying to put dozens of them up to cut off a bear drive. I can actually kind of see a use for them for turkey hunting. Some fools who try to stalk gobblers that actually walk up on other hunters might be stopped if set up correctly.
I have taken 2 hunting vests and put turkey hunter in area on them. I have been doing this for about 8 years now. All I do is wrap it around a tree. I started doing this when I was shot over doing turkey season by a guy moving to a new area to hunt and kick up my tom and took a shot.
