i've imported the 2009 tiger county boundaries for Hawaii.
(http://www.openstreetmap.org/browse/relation/166563) i was incorrect
when i said there are no tiger state boundaries, but they correspond
exactly to the county boundaries. i agree with apollinaris, some state
data that may have been imported is probably still going to be better
than tiger. but to clarify, i don't see any county boundaries that were
imported from the tiger datasets (us census bureau) which are
1:100,000. it looks like most of the existing counties were imported
from the usgs national atlas dataset which are 1:2,000,000.
