Live and let die Meme trends happen, so please don’t message mods asking to take down maps that are repetitive to a bit.
Reposts Vs. Covers Not all reposts are evil- if someone posts something that has been done years ago, it serves to bring old memes to the new users. I call these meme covers. However it can be done in excess which makes it a repost and spam. Mods will determine if a post is a cover or a repost.
No impersonating mods I can’t believe I had to make this rule.
No harassing mods on an appeal We can talk it out, and we will be acting in good faith when making decisions. If you disagree with a removal, you are free to message for clarification or to appeal by giving some added context.
Bans Bans will be set to a maximum of 365 days for humans, and a minimum of 365 years for bots. I believe people can change, so if you are banned for good reason, do know that it is not permanent, it is just a way to say “take time to grow and come back when you are ready”.

Yes! Man created.
The Illinois & Michigan canal was in use until 1933 with the completion of the Illinois Waterway. The Chicago Sanitary and Ship Canal is what reversed the flow of the Chicago River as, as another notable change that reduced traffic on the I&M canal.
Now the I&M canal is a series of walking paths (locally called the “tow path” because that’s how they towed the barges on the river).
Remember that time they accidentally flooded downtown? Chicago has a fun history of architecture and city planning
Here is one of my bits of Chicago trivia. Ridge road is one of the oldest roads in Chicago. If you drive down it, you will notice there are a lot of cemeteries along the road. That is because the ridge it is named after is the beach dune from the old shoreline when the lake stretched further inland during the last glacial period. The cemeteries build along this road because it's easier digging graves in sand.
That is some FANTASTIC Chicago trivia
I actually don’t know about that! Cities are fascinating. Isn’t a chunk of the waterline built on debris? San Francisco is too. Push it into the water and build, it’s fine.
Another interesting thing about Chicago is how the stockyards emptied into “bubbly creek,” which is why it’s named that. There’s a few feet of animal fat still bubbling at the bottom.
Shame on me for having never read The Jungle, I had no idea this existed
Interesting to note that the rotting animal bits causing the bubbles are OVER A HUNDRED years old. Holy fucking hell they had to have dumped a lot in there
That sounds like some of that carbon might have been successfully sequestered.
I recently learned one of the reasons they dye the river once a year is to do leak testing.
