You can pick it up only if a police officer writes a permit for you. I have done it a few times and I had a CO and a local cop write them out for me. The CO said you can pick them up too as long as you use one of your own tags on the deer.
Do we have to report it to the DNR?
What do you have to do in order to cut the tails off of a fresh road-killed deer, fox, coyote, raccoon or squirrel other than be quick? I occasionally tie my own flies to fish with and some of the recipes for flies requires the hair or fir from those animals. I do not want the entire animal, but just the tail.
