i've lived in two of the cities so far mentioned, and know friends in several others. i won't be making my final decision for a while, i'm just making a broad list of cities that would suit my needs of a car-free lifestyle, since car dependence is prevalent in most us cities. i would say that in most places, if you don't have a car, you are not going anywhere at all, and are pretty much at the mercy of those who can drive. i don't want to just survive in the city i'm living in, i want to thrive in it. and also, i am tired of the suburbia experience of america, i always desired a small town-ish feeling, with a big city nearby so that i don't get bored and can keep exploring the area without the dependence of a car. for instance, i think chicago or new york or a few other places, some people don't even own cars and they can get anywhere they want in the area, and even getting out is simple.
plus, it will eliminate any car insurance that i would otherwise pay. fyi, i don't have a driver's license, but intend to get one just so i could get a rental car out of town if needed or have to drive in certain situations.
