We have been discussing potential problems with porcupines, mostly concerned about damaged gear. But in Utah the other day, an 11 year old boy was snatched out of his tent, carried off in his sleeping bag and killed. A similar thing happened in Utah a few years back, but the teenager escaped with only injuries. In NC a year or two back, a mom and her small children were at a popular campground swimming hole, when a bear walked out of the woods and killed one of her children. And I can think of a couple of maulings in the smokies in recent years, on backcountry trails. I can't remember if deaths resulted. We Pinatas need to be cautious.
These were all black bears, no Griz.
