It looks like the map makers ignored Broomfield.
Isn't it that little hook at the southeastern edge of the 2nd district? Or am I giving too much leeway for clumsiness in drawing?
The original city of Broomfield was on the Boulder-Jefferson line just west of Adams, so the part of 7 that goes underneath Broomfield would be in Jefferson County, above the chunk of blue added to the NE corner of Denver (Arvada? and Wheat Ridge?) Perhaps the map-maker exaggerated the width of the corridor to make it look more connected. It also isn't clear what he is doing with the Adams part of Aurora.
