They're off to an early start on their New Year's celebrations, perhaps?

[Rightwing Conspiratr1]

Tofu farts?

[Red Badger]

I’d be looking up for brimstone falling down from the sky.................

“Why Does San Francisco Smell Like Sulfur?”

Because that’s what brimstone smells like. With that in mind it’s time for the good people to leave San Francisco and not look back as they leave.

[lgjhn23]

It’s boiling up from the Pit of Hell...
Wait till the fire & brimstone start falling in Biblical proportions....LOL

[Publius]

Not sulfur. Sulfide. Big difference.

[joshua c]

Someone is spreading sulfur to cover the human waste smell?

Anyway you look at it, San Francisco stinks!

[dhs12345]

Its the many druggies and winos peeing on the sidewalks.

[Zathras]

Not usually a good sign.
I’d get radon monitors in place ASAP
This can sometimes be a precursor of a shallow quake of sizable amplitude.
A jump in radon would validate it as a clear possibility.

[Vaquero]

Poofter butt malodor.

[Minutemen]

Rotting liberal trash.

[dfwgator]

I thought it smelled like ass.

[SGCOS]

Here in Colorado there are a few hot springs that smell like sulphur.

the strongest one I know is in a town called Hot Sulphur Springs. Wonderful spot to relax, once you get used to the sulphur smell

perhaps some new cracks have opened underground and you're smelling hot sulphur..If it is flowing underground, it could explain why the smell seems to be moving also

[Swordmaker]

Gateway to Hell opened a tad earlier than expected?

[smokingfrog]

Leave now, before it’s too late. (and don’t look back)

[TheErnFormerlyKnownAsBig]

I drove semi-near there this last week...down I-5 on way to San Diego.

There was a strong sulfur smell along I-5 both of my trip down and on my way back

[bayliving]

I saw where there is an underwater volcano erupting off the coast, almost due west of SanFran and that that is the likely cause of the smell.

Dunno... Seems plausible.

[trebb]

That ain’t regular sulfur - that’s brimstone sulfur...

[American in Israel]

Two days after a earthquake swarm in a new area due east of San Freasicko. I would suspect hydrogen sulfide venting as the magma rises in the major fault under the city.

[SaraJohnson]

H E double tooth picks.

[Duchess47]

Earthquake coming.
