Dale, you are required to show your Furtaker license when selling furbearers in Pennsylvania.
At that point the fur buyer takes your Furtaker license and records your information (Name, address, license number) in his record book.
Yea guys I hear ya, it's not fun skun'n, flesh'n, sewing rifle shot or road killed fur. Many times you get started and get to damaged area and it's taking alot of time and wondering why am I doing this. Only to get to the damage and figuring it's not worth my time and tossing it out. Also very, very messy process, for the most part.
