Spiders and Webs

As soon as I woke this morning and saw the heavy fog I knew that there might be a chance to get some  interesting shots on my morning walk with the dogs.  I grabbed the camera and off I went.  The first thing that I noticed was the cobwebs.....everywhere.  The stringy kind that you walk through and they cling to you.  How do they get there and what spiders build them?  I will have to ask somebody knowledgeable about that one.  Here are some photos that I took.
