Most states have a trappers association that host a fur sale. I took a quick look and noticed the Virginia Trappers Association on-line. These loccal associations are a great place to start for selling or finding local fur buyers.
Bulls Gap in northern TN has a fur sale sometime around the end of Feb every year. It's a good sale. I used to sell there every year and got pretty good prices. I would check the laws and see if it were leagal first thou.
