I'm Canadian ,(west coast) on Vancouver Island. I got the U.S. west coast easily enough but it got a little tougher back east... I ended up with all but a few.
I believe that bit of land above Wisconsin is called a ruse. I eventually passed. I think I could have done better if I hadn't been using a notebook computer. The little touch pad mouse was hard to manipulate on those little NE states. That and it took me forever to remember which of those little ones was which.
