Subway sleepers

In every train car on the subway there is at least one person who is sleeping. It's actually pretty comical to watch them. Usually they sit up and let their head roll forward. Sometimes they fight the head roll and do a continuous head-nod as they fall asleep and awaken over and over again. The funniest ones fall asleep and tilt to the side so that they are sleeping on the ungrateful person next to them.

The picture below is of a man in a deep sleep. When I first noticed, the dribble of spit on his lip was like a raindrop. I immediately pulled out my camera, aimed, and snapped the picture. To my delight I caught the dribble when it was a couple inches long! Unfortunately, the train was at a stop and began moving at the same time I took the photo, so it is a little blurry.
