It seems like I hear every sound in the woods when I'm walking in the dark. I've had the crap scared out of me (almost literally) by a deer blowing, snorting, and wheezing about 5 yards away from me before crashing off through the woods. The only time I've been scared during the daylight was when I was hunting in Texas. It was early in the season and just starting to cool off, as I was walking back to my truck after a morning hunt I stopped to take a break. When I looked down, there was a rattle snake warming itself on a flat rock only about 3 feet from where I was standing.
