I was recently backpacking the AT and there are 2 bears per square mile in the Smokies. It is a complicated problem. Improper food hangs, cooking in camp, habituated bears, day hikers feeding the cute bears, etc.
During TABR, there was a huge flashing sign at the bottom of totawotte pass in wyoming saying there was Grizzly with cubs at the top. Scary sight is all I will say.
