I saw this article at BoingBoing, and had to look it up.
From Wikipedia:
The Aroma of Tacoma, also known as the Tacoma Aroma, is a putrid and unpleasant odor associated with Tacoma, Washington, United States.[1] The smell has been described as similar to the odor of rotten eggs.[2] The odor is not noticeable throughout the city, but is rather concentrated in the Tacoma tideflats and is frequently smelled by motorists traveling that section of Interstate 5.[2]
Is it sulfur releasing from the volcanic activity?
Article says paper mill pollution and sewage
That is equally depressing and disgusting.
Volcanic sulphur isn’t that bad, you get used to out petty quickly.
Some very still mornings it I can be quite strong…
