Imagine it is late in the day and you are inside your cottage at your weekend retreat leisurely preparing a bite to eat. Gradually you notice that the atmosphere in the cottage is changing. You have seen this many times and know that it can only mean one thing; a special event that cannot be ignored. You stop everything, fix your favorite beverage and head out to the back porch to sit back and enjoy another edition of the always-unique setting sun in the western sky as in lowers below the horizon of the marshland.
