I am going to have to look hard myself. I used to take the hides into a fur buyer in Springfield who would show up at a designated car lot once a week.
The last three years I would give my hides to a co-worker and trapper who would ship what I had along with his. This guy has since moved to PA.
Graybeards advice is good as you could check the trapping forum here or better yet, try to contact your local trappers to see where they are selling.
