Seaside Escape

You saved all year for this vacation and it is finally here! The perfect cottage you found gives you peace and solitude, yet is close to all the action and amazing food. Yes, FUN is what you have forcasted for the week. Unfortunately, upon arrival, mother nature changed the forcast with a hurricane watch in effect, torrential rains, and high winds. You have been stuck inside...wishing to get back home. While waiting for your ride (who is about an hour out still) you notice something you hadn't seen all week. What is it? What does it mean? and why hadn't you noticed it before?
