Another reason an on-campus ANC race tied 1-1? Incorrect ballots (
It’s not clear exactly why the voter registration system defaulted to putting people who should have been in 3E07 into 3E08, instead of, say, the other way around.

This is an amazing story. I don’t live on campus, but when I did the mail system was a constant anxiety.

AU’s mail system is a walled garden; letters are passed through a central mail room before delivery to their building. It just isn’t designed for geographic accuracy. A district splitting the campus and its one mailing address in half probably was not a planned edge-case.

My hypothesis is that the Board of Elections’ system saw:

4400 Massachusetts Ave NW
Letts Hall 100
Washington, DC 20016

as the same as

4400 Massachusetts Ave NW
Washington, DC 20016

If this is true, I’m not sure if it happened at the time of registration or when the ballot was requested.

The USPS has some awareness of the campus mailing system. Searching the ZIP Code Lookup Tool for “Centennial Hall 400” with AU’s 5 digit ZIP code resolves to a mailable address.

Biohazard: Iconic Symbol Designed to be “Memorable but Meaningless” by Kurt Kohlstedt (99% Invisible)
Before uniting behind a single symbol, scientists working with dangerous biological materials faced a dizzying array of warning labels that varied from one laboratory to the next. Then, in 1966, Charles L. Baldwin of Dow Chemical and Robert S. Runkle of the National Institutes of Health co-published a critical paper in Science. Their piece called for the adoption of the biological hazard (or: biohazard) symbol as we know it today. This new symbol they hoped to become standard, however, was unconventional: a crowd-tested solution designed to be maximally devoid of obvious meaning or associations.

Why doesn't Costa Rica use real addresses? by Alejandro Zúñiga (The Costa Rica Daily: Costa Rica News & Travel)
Costa Rica uses an idiosyncratic system of addresses that relies on landmarks, history and quite a bit of guesswork. My apartment, for instance, is three houses down from the local high school. The high school’s official address is 300 meters east of the elementary school. The elementary school’s address is across the street from the church — or next to the bar, depending on your piety.
