You know the county uses a numbered grid for roads and you've deduced that the placement of the directional portion (SW) is what tells you if it's a north-south road or an east-west road.
To make matters worse, the King County grid is so wide that in neighborhoods like ours, there are plenty of streets that run in parallel with the same number but a different street type.
So you decide to go and grab some food from a nearby fast food restaurant. And then encounter this on the way home. In the dark.
I'd almost forgot about that until I came across this last week - years later.
As if that wasn't bad enough, they have to frustrate my CDO by putting punctuation on one but not the other. Torture.
