Have you ever noticed the line of shells and seaweed running along the sand that is left behind by the high tide?  That's called the wrack line, and it's full of interesting things that you probably never even knew were there.  Join a Fire Island National Seashore Park Ranger at FINS Smith Point to learn about the fascinating aquatic life that washes up on shore.  Participate in a Wrack Line Scavenger Hunt and see what you can find.
