How the States Got Their Shapes

The first season was amazing, I loved it. Something very strange happened in the second season though, it adopted a cheesy game show type style and VERY centralized around the Midwest. Every episode in the second season seems to have something to do with the Midwest. What about the other states? Yeah, they are mentioned but not explored in depth. I've heard them talk about Wisconsin, Iowa, Michigan, Ohio, etc., what about Oregon, Washington, Montana? Hell, California has only been features once or twice. Maybe the boarders are more interesting in the Midwest but you could still talk about the other states more. Maybe I'm wrong and have missed something but it just seems like the producer of the show loves the great lakes area.
