The world's largest lake, located inbetween Canada and the USA. States linked to Lake Superior are Minnesota, Michigan, and Wisconsin.
On an important note, the reason for the hypocritical weather (IOW : constant weather changes here & there) in these states is because of Lake Superior. Apparently, from a non-scientific perspective, the lake is so large that the atmosphere around it is changed rapidly, so you may never know what the weather may be like, regardless of what weather reporters tell you.
"Lake Superior is also shaped like a monster's head."
