Those are red oak. The beaver can just get so far.
That pond was fun to trap. It is in the woods behind work. We had questionable inches of solid black ice. . The lodge was on the other side of the river. The only way across was an acrobatic walk across the dam. The bubble trails from the lodge looked like the center line of a highway. One night two traps, two beaver.
I've never trapped there again.
The first coyote I heard was at the now closed dairy farm in our adjacent town in 1977. The fox and fisher picture in the drywall was taken in 1988. We never caught a coyote. The next year 1989 I had to upgrade my equipment. The coyotes appeared and started testing my traps.
I heated the ends of the jaws on my 1.75's Victors and bent them up so the coyote couldn't pop the jaws. Each trap got an inline swivel. All the traps were equipped with double stake swivels. While some traps were retired after catching a yote, I ever lost a coyote to 24" of double staked re barb.
A growing human population with their dogs and cats made me choose a different path. My NH canine trapping was over. From there I went to water which I enjoy the most today.
I caught fourteen otters this winter. Set a beaver trap.............catch an otter. I had two doubles that season and caught six where the fresh water meets the salt.
I'm glad I did it when I was a young man.
