I do the same even though ours are not metallic during bow season. As for gun season it remains on the back of my jacket.

Against it, our PA licenses are shiny metalic licenses. You sould see the shine off of them. I'm a fanatic about that in my treestand, law or no law, I wear my license on my backpack and it's hidden against the tree when I am in it. I figure with I'm walking, I'm legal...same goes for turkey hunting, when against a tree that is too small and that shiny license on my back...I don't think so...it's in my vest. I consider it dangerous if someone sneaks in behind me or just dumb in a gobbler sneaks in behind me.
