In this photo you can see by the look of green where Detroit’s city limits end. The darker area is trees of suburbs. Detroit lost most of its trees in the last 30 years [almost all street trees were elms, which were destroyed by “Dutch Elm Disease]. The bridge crosses the Detroit River and is called the “Ambasador Bridge.” It crosses the river to Windsor Canada. Beyond at the top of the photo is “Lake St. Clair.” It is about 500 square miles and is full of ice.
