Seems like 20% normal disagreement, 50% dunks, 20% agreement, and 10% this stuff.

It makes me very angry that the new @citybloomington.bsky.social greenway, which we spent a million dollars on, is entirely blocked here because not only has it not been plowed, but the city plowed snow _onto_ the path at the end.
