As a teen, I used to do this regularly in some woods in northern MN. On a moonless night I could navigate by looking up to see the stars through the gap in the trees, indicating the trail. I had many interesting and wonderful experiences— once a flock of whistling swans flew over and I saw their silhouettes pass through over. Another time I a startled a deer (and vise-versa) only a few feet away and it let out a terrifying scream. Another time a flying squirrel landed on my face while I was standing still.
