We took the trail to Cub Lake, which is an easy one, but rather long. (6
miles.) We ate lunch on a rock by the lake, and didn't notice the duck
asleep on a rock no more than 12 feet away from us, until he woke and
started stretching. He ignored us as he washed and preened and took a
couple sips of water.
