The Chicago closeup has a confusing combination of a time zone line and dotted line. Still it is nice to have the time zone lines.
Paper maps are my favorite thing to put on the wall. My favorite right now is a map of the Appalachian trail. A tall, very narrow map, it cuts diagonally across the traditional map of eastern America, giving a very different perspective.
Because the river actually IS the defining border for the state, on the Imus map the river is highlighted in blue underneath the dark-green that depicts a state border.
A much better design decision IMO.
