I was going to share a helpful hint for the new guys, and maybe even an old guy or two that I have hunted with and frustrated me no end. When you are hunting snow that is dry and hard to ID, here is something I do, that again, saves time. Most guys will not do it because you gotta get off your duff to do it, but I guarantee it will help speed up track ID under certain conditions. It is from a book called "Hunting Bobcats and Jesus with Dogs"
When you are approaching a track coming across the road that looks like it has cat potential, stop your vehicle well before you get to the track. Get out of the truck, and walk up to it to study it in the road before tampering with the evidence with your rig.
Very often the clear print you are looking for was in the road before you messed it up with the truck. Even if there was a clear print on the berm, the action of the truck can blow that dry snow into it. But often, there never was a clear print anywhere but in the road. The tracks you do not completely wipe out with the tires, will be blown in by the movement of the truck.
Often, you can get a better attempt at aging the track also. If there are old tire tracks with some snow in them, this is where you will get your best print, and age. MOst of the time, the cat will put down in that tire track. IF it shows up in the new skiff of snow, obviously, he walked since the snow, and the track will be pretty like a picture. If the stride shows him stepping in the tire track but the track is missing, well there is some more info about time. He walked before the skiff of snow fell.
IF there is no new snow and his stride puts him in the tire track, and there is no track there, look again! You gotta go from seeing a mess in a bunch of snow to seeing almost invisible outline on a hard surface. Often though, once you get your eyes changed over, you will see the very certain outline of the feline, complete with the "w" in the heel.
If there is a tire track there, and the bobcat stride does not recognize the tire track at all, the other truck probably came through since the cat walked. They were deer hunting or blind guys cat hunting.
All this will be lost in dry snow if you do not stop the truck befor you get to the track

wish I had a shocking collar on you, your trying to trash again

Man do I ever know that look

Those dogs are so much better at this than I am. If you got a dog like that, forget about the above helpful hint. you wont need it
Again, for the new guy: When I am trying to get a young dog to that point, I take him out of the box often to check out all kinds of tracks. It is not really fair to a dog if the only time he gets out of the box is for a bobcat track. They can not learn discernment. What if the last ten tracks you took them out of the box for were rip roaring good timing, full speed ahead bobcat tracks? Then the eleventh track is an unidentified coyote track. Guess what, it will be a rip roaring good timing, full speed ahead coyote track. But If two out of the last ten were bobcat tracks, the young dog will understand some sense of responsibility when he is taken out of the box.
