Sept 7 thur 9th

Sept 7th and 8th Doing odds and ends and travel.
Sept 9th We are now in Duluth, Minnesota, the drive was beautiful with all the Sugar Maple and Birch trees changing color. The Birch tree is the weed in the North woods, when they cut down the pine, maple, and tamarack tree the Birch tree reseeds and grows wild.
Our campground is on an Island in the middle of the city. To reach our Island we have to cross a steel aerial lift bridge that's 138 ft high and 336 ft long. (picture) The campground is in a marina right on the water. We enjoy the shops and the restaurants that are on the other side of the bridge. Sharon took a picture of the jetty light through the steel bars of the bridge when we walked across for lunch.
Our parking space is used for large yachts during the winter so it is right on a pier. The marina is full of fishing, sail boats, and yachts that we can see from our window. We can see the city lights across the water and also view the bridge while sitting at our dining room table.
The bridge allows large grain and gravel ships to enter and leave the harbor. When the ships leave the harbor they sound their horn and depart under the bridge for lake Superior and the ocean. We saw a over 500 ft long ship leave the harbor for the Atlantic ocean.We were amazed to find out the elevation of Lake Superior is 602 ft. This means that the ships that enter and leave Lake Superior must enter 14 locks to reach the Atlantic Ocean. That takes about 8 days for the ships to get through the locks. It sure didn't look all that difficult when we watched them sail by.
