I'm pulling my hair out with address etiquette! I live in DC, as do a lot of our guests. I know that it's the only exception to needing to spell out states, but I still plan to address to "Washington, District of Columbia" because I like the way it looks. But does anyone know what to do about the quadrants? I know that the standard rule is to spell out street directions, but I have never, ever seen a DC quadrant spelled out before. Here's what my instinct says:
Ms. Jane Doe
123 H Street, NW
Washington, District of Columbia
