I don't get the ChiPitts (or is that Chia Pitts?

) one either. What connects Chicagoland to Detroitland (I just made that up) There's not much between the two areas except a huge lake and farms and rural areas, with an occasional small city in between. It isn't the same, or at least doesn't appear to be the same to me, as what exists in the Boston to Washington region. Am I misunderstanding what it is? (Yes, I learned about it in Elementary school in Michigan, years ago.)
