As a city dweller who won't stray more than six blocks from a 7-eleven, I find the woods terrifying even in bright sunlight. Not sure what's scarier: the potential bear attacks, or the lack of access to Diet Coke and protein bars. The woods at night is another level of horror I can't even begin to imagine. But there are people who venture into the woods after dark of their own volition—for "fun"! And many of them have even survived to talk about it.

Breathing... just heavy breathing right outside my tent loud enough to wake me up. Not like fat guy going up the stairs breathing. Very large intense clear breathing. Middle of the night, no animal sounds no grunting no foot steps, just breathing from something large. I loaded my shotgun and pointed it in the direction it was coming from and waited for what seemed like a lifetime (probably 2-3 min) until it just stopped.
