I love the woods at night! The only thing I ever worry about is other people.
When I was young (like 15) I thought I was a pretty cool character walking the woods in the dark early morning hours not worrying about anything until the time I walked about 10 yards from a bobcat who let me know it was there by emitting a blood curdling 'scream'. At the time I didn't have any clue what a bobcat sounded like and I was pretty sure some nice lady had just been murdered right next to me. Not a sound I will ever forget. I think that's the most scared I've been in my life.
For your health.
