ok, i have a couple of comments now that i've seen it.

first, it's from the import of 2008 tiger admin boundaries. it'd be
worthwhile to compare it to the Willits polygons from the 2013
tiger boundaries. some have changed, others have not.

second, none of the polygons have roles. it looks to me like they
should all have role outer, as there seems to be Willits proper and
3 outlying areas. i have added the missing roles.

third, if the 2008 boundary is correct, or close to correct,
then probably someone wanted their property to be annexed by the
city for some reason. these things happen.
