You know those cities that futurists like Jacque Fresco design? (Think like what Epcot was supposed to be ebfore it was a park.) I'd like to live in one of those, except I'd want it less creepy Big Brother and more eco-friendly/green.
There's an interesting book I read that I can't remember the name of now, but it basically talked about building cities where the emphasis was on being environmentally AND people-friendly, where urban sprawl was minimal and the quality of life was high. The designs had all sorts of plants, parks, and other green places running throughout, and it just looked like a really nice place to live.
