I hadn’t thought about it being quieter, though living where I do it is already pretty quiet. In a world without the grid, it would definitely be darker. That will be hard on urban folks especially. There was an article in the paper where I used to live in MA a few years back about urban folks from NYC who had 2nd homes in Western MA. A common theme for them was that they were terrified of the dark at night and didn’t want to go outside. I found it humorous that these folks weren’t afraid of the human predators in NYC so much as they were about wild animals in the forests outside their homes.
