HAIKU_220330_572
Existing comment: I used a map of the Golden Triangle BID boundaries from Wikipedia to figure out what blocks I had to walk looking for the Golden Haiku signs. There were restrictions on putting signs on blocks in front of federal / international buildings or on National Park Service grounds so many of the blocks were totally void of signs. (The area south of Pennsylvania Avenue, for example, had no signs except for Pennsylvania Avenue itself.)
As I explored blocks, I marked of each sidewalk I covered. This was the map as of my fourth scavenger hunt on April 1 -- northeast of the White House -- during which I found absolutely no new signs.
I've only found 190 of the 200 unique signs so I might try the few missing segments later.
