Mouse tracks turning right

One of my favorite things about winter—OK, call me crazy, but I have a lot of favorite things about the cold times—is that it gives me a chance to track animals. I'm not particularly stellar at this, and I certainly can not, as the true Deep Trackers claim to be able to do, read the mind of a bird or mammal, even to merge with its spirit, simply by following the trail it has left in fresh snow. I guess I'm spiritually underdeveloped. I can, however, discern that this set of tracks was made by some species of mouse. The small size of the paired foot marks, along with the tail it dragged on the snow surface, give me its rough identity. And I can tell that it was moving left to right. Beyond that, the mission that made the mouse abandon its relatively safe subnivean tunnels for the more risky business of traveling on the surface, will have to remain a mystery. That's fine—I love a good mystery.
