I live in Flint now, and I'm a fan of this. Shrink the city, it is way too big. It will allow a few positive things to happen. The city could rebuild a sense of community, it would be less taxing on support services such as fire and police, and it would not be such an ugly place with it's rundown empty neighborhoods breeding crime. The downside is it will push the shithead criminals into my back yard.
I could live with more nature. Less urban blight isn't a bad thing.
