Around here this is actually not all that uncommon. Sometimes the hunter or hiker knows they are being stalked, sometimes they just find tracks following theirs. The latter has happened to me w/ wolves in my ski tracks.

I know a number of fellows who have had mt lion interactions similar to the above. One is a dear old friend of mine who was a real estate agent who heard a "PLOP!" in the snow behind him as he was checking some property one day. As he turned slowly around he drew his Smith and Wesson 28-2 .357 Magnum "Highway Patrolman" and had the gun up when he made the full turn and there was a lion crouching in the snow facing him. He planted one shot in its face and the thing blew up off the ground, took off running thru the snow spraying blood all over as it ran.

Years ago I told him not to sell that wheelgun before giving me first option to buy. One day I found a box marked "Dirty Laundry" on my front steps, opened it up and...there it was... No charge.
