I can go back that far too.
I averaged more for Reds, then Greys, in the fur boom years.
I walked out on Dutch in those days, and didn't sell to him. Did better with Erdly in Middleburg, Reeder in Sunbury or Hess near Danville.
Back in the fur boom, I never heard of a Pa. Trappers Association's District Fur Sale. They may have hosted them, but I never heard of them. I started going to them in the late '80's or early '90's.
bearhunting, I think Dutch was in 3 different locations during his career as a fur buyer. Are you with me?
