Yep, just a few months ago in Utah, that young child was surgically removed from his tent and partially eaten a few hundred feet from the tent by a black bear.

In the Alaska grizzly killing of the couple sleeping in their tent on the banks of a river a year or so ago...someone in the vicinity after the killings was stalked by the same bear. The person was in a boat and the bear just kept following along the bank waiting for a way to get at them. Those stories are scary.
