Yep, I can see that you and your partner were running it hard, and I know the routine of which you speak.
Man O man, those December 'coon sure are nice!
Years ago, I had a partner, and we hit it in the same manner. We trapped the West Fork river in WV, and because of steep banks, we used a john boat. When it came to skinning, my partner would open 'em up, and I would pull 'em out. We got pretty handy with that method. We rolled up the green skins that needed fleshing, and put them in plastic bags, and into an old chest freezer. Then when we stopped trapping for awhile, we would get them out of the freezer, and flesh and stretch. 'Coon fat and beaver flesh scrapes nice that way.
Because of our day jobs, most of our trapping was on week-ends like yours was.
Most of our winter trapping was on land, and we took a lot of fox in the fur boom days. Then, later on, the coyotes came along, and we hit them too. The thing with the 'yotes was (as you probably know) that we had to cover far more territory, That worked out ok though, because in getting all those permissions, (which the land owners were only too glad to allow) I can now 'seng on a lot of properties here locally.
Sadly, my ol' partner is now deceased, and in the last few years, I have trapped sparingly. I'm not trapping at all now, but I am 'senging more, and as you know, just starting into the 'growing' venture.
PS: Most of my guns have come from fur money as well.
