My commute takes me from Bainbridge Island, over the Sound, across Kitsap and King county lines, into the Democratic Republic of Seattle.
Borders can be like shadows on a city street.
We cross from dark to bright sun with little regard to our changed environment. But borders matter. Just walk from the shade into the sun and feel warmer, even on a cold day. The difference in the tax rate from one county to another is similarly subtle. Buy a television in Silverdale and pay slightly less than you would in Seattle.
