You are currently standing at Seattle and starting a journey to walk around the outline of US i.e. along Borders and Coast, in a clockwise order. Can you name each and every state you will pass through in order?
Great Lakes are consider to be on outline of US, hence states touching Michigan Lake are included.
I was confused around Michigan, Ohio, Illinois, and Indiana. I wasn't sure what came next. Otherwise nice idea! I'll think on how to make instructions more clear.
