True, wolves have attacked humans on occasion, but it very rare, and it sounds like these guys were just checking you over. They knew you were a human for sure. Had they wanted you, you wouldn't be here now.......which says, well, they weren't interested.
Not surprisingly, you, I and everyone else, have a greater chance of dying from an MVA each and every time you climb into your vehicle and drive than from an attack from any animal. Statistics don't lie. We just don't contemplate the odds of crashing and injury before we drive. Have you never had "a near miss" while driving? Hummm.
One critter I am extemely vigilant of while in the bush is a nest of angry hornets, particularly the ones that nest in the ground. During Sept. scouting excursions, I've stirred them up on more than one occasion, and trust me, it doesn't take much to agitate them. Just walking unsuspectingly with-in 10 feet of the nest will do it. If you are at all sensitive to wasp venom, which can occur over a period of years, just one sting can result in anaphylaxis and it could game over in short order. Now, imagine 50 or more stings? Even without a sensitvity, you may or may not survive. When I stumble into a nest, I beetle outa' there and fast!
You got to see a wolf pack at close range.....cool! Many people will go a lifetime in the bush and never experience that.
