When I started the US state border import (which Adam finished), I expended quite a bit of manual effort splitting borders to not make them overlap. AFAIK, the complex multipolygon stuff didn't exist at that point, or I probably would have tried to use it as well. I don't think there were national borders in at that point, although I could be misremembering. And then Ian tossed the county borders in wholesale (which made me cry a little, I admit), and of course none of these datasets quite line up. I've done some fixup locally where I cared about, but it surely needs some love. -Ted
