I do not think there is anything to gain from the counties that are listed
to not be improved.  My county (orange county fl.) is one that was NOT
improved yet, and in QGIS it looks to be unmodified from the original tiger
import.  There are not any new tags in the data that would add anything
either.

Orange county Fl. does not have dual carriage ways, but Lake county Fl.
which was updated does have them.  I have looked at the current county
files, and the same is true.  So I'm not sure it is the tiger improvement
making it dual carriage ways, or the fact that the source county has them as
dual to start with.
