If your state is like KY, then you'd better have an ink pen in your pack. We have to use it to mark our tag with info about the kill before we even move the carcass.
In addition to the pen, I pack the following when going out for an evening or morning whitetail hunt:
Finger tab, arm guard, headlamp, camo tight-fitting head-net and camo "do rag" head covering or fleece head cover if it's cold, safety strap to attach my harness to the tree, pull-up rope, grunt call, and Buck model 501 lock-blade knife. All this in my fanny pack. Of course I have my wallet with my hunting license/permits. Sometimes I take my binos, but not always. I always take my cell phone and keep it in a shirt pocket underneath my coveralls. If I arrow a deer, I immediately call home and I also call my bestest hunting friend. After I recover the animal, I send a picture to my hunting buddy and call home again!
