Walking today we ran across some street maintenance.


I got to thinking about how low-tech cobblestones are. The stones look easy enough to make. We saw some being installed: they just grab one, place it in the sand, and tap it with a hammer to position it. No hot tar. No big cement truck. No waiting for it to dry. It is a cheap and easy way to maintain streets and sidewalks. And small repairs are easy. And, they last a long long time.
On the downside they are not as nice to walk on as asphalt or cement in terms of tripping.
According to ChatGPT true cobblestones are not cut or shaped but collected. What I have been talking about are setts or Belgian stones.
