Sam, I was out this morning, just to check travel route for prints. There has been no movement since the snow fell as far as "prey" animals. Places that are full of rabbits have no prints yet at all. They are holding tight right now and have been all night. With another frontal system coming, Hopefully this evening/afternoon will be the key time.
Remember close to their cover. In it if you can find a shooting lane. Afghanistan would be a good choice, close to the "edges" of two or more covers, where it is heavy.
