I don't think I have ever used my tracking skills as much as I have in the past week. And I thought maybe it would be appropriate to test what talents the rest of you have in interpreting track sign.

So here's your quiz. What can you discern from the tracks in this photo?

Need a little help?

Okay, first, you will notice the small tracks in the foreground appear to be those of a canid, running up to meet the larger tracks of a booted human, which has just scaled the interstate fence.

The interesting thing is, the canid tracks seem to disappear completely at this point.

And those of you really astute at this may notice the boot tracks of the human seem just a little deeper on the return trip back to the fence.

As though the human had suddenly gotten 25-30 pounds heavier.

The following photo is not part of your quiz. I just thought some might appreciate seeing the masked heeler checking out the bed where her maskless sister spent the night of 11/12 February, which reached a record low of -21 degrees.

Not much protection from the elements there.
