I was checking out a new Conservation Area last year, walking up a trail, looking left and right into the woods to see what was there. The trail kind of dead ended, so I turned around and started walking back. About 15 steps on the way back I am looking down and there is a 6-8' rattler lying in the trail sunning himself. He had to be there a minute or so ago, so I must have stepped right over him, made the hair stand up on the back of my neck.
On the bobcats, a few years ago I saw that movie, Blair Witch Project (usually really don't like that genre of movies...) and went camping the next night. We had a bobcat circling the campground, and that was the single scariest sound that I have ever heard, sounded almost like a baby crying.... don't think I slept 10 minutes all night after that.
