I live in the suburbs now. It seems to me when I used to live in the city, I wanted to l=get away from it all and live somewhere quieter and greener, and now that I do, I sometimes actually miss the city living.
It was easier to get around in, more options as a consumer, and yes it was even more community focused than I find it up here.
Where I live now, I have lived for over 4 yrs (not this house but in the suburbs) and I haven't made friends as easy because everyone already knows everyone and it's quite a close knit, no room for new people, kind of place.
In the city it was easier.
However I make myself feel better by convincing myself that it is better for my kids.
