my state requires back tags for deer season only,i think one big reason is to stop poachers, the d.n.r. are able to check hunters with binocs to make sure hunters are legal.i.e. different color every year. i would rather be checked out from afar instead of having game wardens disrupt my hunt by walking up on my blind or treestand. we have alot of poachers here in wisconsin, so i have no problem with it. besides, you can't even feel it on your back, and it doesn't make any noise.
