That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

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]

HAHA!

A Garlic Aroma that would level Tacoma.

Hell if you want to go somewhere that smells, go to Lubbock Texas. It is from the Oil industry, holy fuck it stinks!!

[–] sunnie@slrpnk.net 4 points 2 hours ago (1 children)

Petroleum processing is a whole other level of stink. Every breath feels dangerous to take and not just unpleasant.

[–] IWW4@lemmy.zip 2 points 2 hours ago

Yeah! That is a good way to put it. There are stinks, but the aroma of petro processing is an assault!

Wisconsin unofficial motto: Come Smell our Dairy Air

people might also be interested to know that downtown Chicago used to smell like brownies because of the Blommer chocolate factory that was there from 1939 to 2024

Boston sometimes smells like molasses in the summer from a molasses flood back in 1919.

[–] sunnie@slrpnk.net 4 points 2 hours ago (1 children)

I’ll just leave this here, because it’s so fascinating. Can you imagine a wave of molasses traveling at 35 mph?

[–] blockheadjt@sh.itjust.works 3 points 6 hours ago (1 children)

They have a zoo with... aromas too

[–] partofthevoice@lemmy.zip 6 points 6 hours ago* (last edited 6 hours ago)

You mean the Oval Office?

Edit: damn it, that’s the state.

Sonoma county California smells like cow shit sometimes and we call it the Sonoma Aroma.

[–] fubarx@lemmy.world 26 points 12 hours ago (1 children)

Used to drive through there regularly. Yep. It was for real. If the wind blew a certain way or there was a heatwave, it was unbearable.

Felt the same way on a tour of a brewery where they were cooking the hops. Except that had a bit of sweetness. The Tacoma Aroma was just stultifyingly, not as sharp as sulphurous, rotten eggs. More like heavy, warm milk that had gone bad.

All day, every day. Everywhere.

[–] TheFunkyMonk@lemmy.world 3 points 6 hours ago (1 children)

I’ll steer clear of Tacoma, but I could live in the smell of hops on brew day.

[–] tpyo@lemmy.world 4 points 5 hours ago (1 children)

It's not a problem really anymore. There's lots of fun things to do in Tacoma if you find yourself in the area. I'm not super familiar, just been through a few times

As another commenter said, it's due to paper mills which use sulphur compounds to turn wood into pulp and those are still common elsewhere in the state

[–] velma@sh.itjust.works 1 points 1 hour ago

Yep, the paper mills have long closed down in that area!

[–] tacosanonymous@mander.xyz 9 points 11 hours ago (1 children)

Is it sulfur releasing from the volcanic activity?

[–] quick_snail@feddit.nl 17 points 10 hours ago (1 children)

Article says paper mill pollution and sewage

[–] tacosanonymous@mander.xyz 12 points 10 hours ago (1 children)

That is equally depressing and disgusting.

[–] absGeekNZ@lemmy.nz 5 points 7 hours ago

Volcanic sulphur isn't that bad, you get used to out petty quickly.

Some very still mornings it I can be quite strong....

[–] Suck_on_my_Presence@lemmy.world 55 points 16 hours ago (3 children)

If you've ever been near a paper plant, then you'd understand the horrible smell.

Driving through that stretch is such a shock if you're not ready for it. It smells like cooking fish and broccoli in a microwave to me. Rotton broccoli fart smell.

[–] gramie@lemmy.ca 1 points 2 hours ago

Saint John, New Brunswick also used to have a terrible smell from the pulp mill. Last time I was there I didn't notice it, so maybe they have cleaned it up.

It's specific to chemicals used in the Kraft process for making wood pulp. Other Mills might use at different process, with their own issues (like SO~2~ gas).

[–] HeyThisIsntTheYMCA@lemmy.world 1 points 5 hours ago

Decayed broccoli fart

[–] thisbenzingring@lemmy.today 9 points 14 hours ago

That is part of it, also the Puget Sound is kinda like pushing everything to the south with the weather and the tides.

Thankfully it's better these days. It was absolutely dreadful in the 70s and 80s

[–] ada@piefed.blahaj.zone 13 points 15 hours ago (2 children)

I've never been to Seattle, but I knew about the Tacoma Aroma from playing Shadowrun for so many years (The default setting is Seattle)

[–] KuroiKaze@lemmy.world 9 points 12 hours ago (2 children)

Tacoma is basically like The place where you get your catalytic converter stolen And no seattleites go there for any reason except maybe to get soul food or attend a rave at the Tacoma dome. Truly the valley the light does not reach lol.

[–] kinther@lemmy.world 2 points 1 hour ago

When I visit Tacoma it's for the McMenamins Elk's Temple. Shows in the basement, food in one of the restaurants.

[–] velma@sh.itjust.works 1 points 1 hour ago* (last edited 1 hour ago)

Seattleites don't go to Tacoma because they're elitists.

We aren't known for our soul food lol

[–] thisbenzingring@lemmy.today 11 points 14 hours ago (1 children)

I'm someone who's lived in Washington State all my life, all over the state. Seattle and Tacoma are like brothers but only if you knew their parents first. Totally different personalities. I lived in Seattle for 20 years and going to Tacoma was always so weird. And people in Tacoma would rather be anywhere in the world than Seattle

[–] ada@piefed.blahaj.zone 6 points 14 hours ago (1 children)

In Shadowrun, they've merged. Not being American myself, I was surprised to discover they were actually distinct cities!

[–] thisbenzingring@lemmy.today 7 points 13 hours ago

They are pretty much connected with the suburban areas between them. Driving on the freeway it's like patches of purposely reserved green spaces but you could easily drive from one to the other in a couple hours by regular roads with business buildings along the way

[–] Proprietary_Blend@lemmy.world 7 points 14 hours ago (1 children)

I also recently learned about this and how it may have contributed to the 100s of serial killers in the 70s and 80s.
