just an fyi for everyone to check out...
in addition to the tiger county boundaries for Hawaii, i added the U.S.
Exclusive Economic Zone
(http://www.openstreetmap.org/browse/relation/279001), the U.S.
Contiguous Zone (http://www.openstreetmap.org/browse/relation/279045),
and the U.S. Territorial Sea
(http://www.openstreetmap.org/browse/relation/148838) around Hawaii.
