Black bears are changing their attitude, by getting accustomed to people. I have a hard time getting used to the fact that they can be dangerous. They used to be known as the harmless clowns of the woods.
My son and his son were out on their quads a couple of evenings ago, maybe eight miles from town. They were going up a narrow trail, steep, rocky bluff below and steep hill above, when they met what my son, who has seen a great many bears, described as a large black bear, walking down hill on their trail. He said they had quite a time getting him off the trail. He said the bear was bound he wasn't going to give up the trail, just for a couple of quads! He said they finally chased him up the hill.
Both of them have good rifles, but didn't have a firearm with them. My son has little fear of black bears, (don't know where he gets that from!) but I think he is getting more cautious. He once shot a good sized bear, right in the eye, with a 22, single shot Cooey, and killed the bear instantly!
