I was out tracking and came upon these coyote tracks. 
The tracks were in this strange lope. It looked like the animal was kicking its rear feet out to the left side ( you can see the smaller hind tracks out to the left). I stood there for some time trying to figure it out, and the image in my mind was of a happy dog swinging its tail as it pranced about the yard.
I followed the trail only a few more yards and found this. 
The whole pack had come together on the swamp ice. 
Here some coyotes had wrestled together. You can see some knees and elbows in there.
