This area looks pretty reasonable to me, except for some disconnected 
tertiaries in Fancy Creek State Park. [1]

In cases like this, I would probably go with my own intuition. In places 
I've mapped, the DOT is less concerned about making a hierarchical map 
than about allocating funding based on the official route network. But 
it sounds like KDOT is really good about classifying based on the same 
criteria as us mappers, in which case HFCS makes for a great secondary 
source.
