For most people living in Montana, especially in areas surrounding Yellowstone, they know they have to be bear aware. However, there are many people who come from out of state to the gorgeous offerings of Montana and Yellowstone National Park. So much undeveloped and natural land, but this also brings the dangers of the wild. Last year 2 hikers were killed in Yellowstone, one after coming upon a sow and her cubs twice, and the other is still uncertain. He did know he was in bear territory though, as rangers had warned him the day before he was killed.
