I live in a town of about 100,000 and being car free here is certainly not easy. It's definitely doable, but not easy. It would be extremely difficult without a bicycle, and if had children it would probably be out of the question altogether. I would like to live somewhere more walkable. I like cycling, but it would be nice to be able to walk for errands occasionally (and not have to spend 2 hours doing it). Hopefully soon I'll be moving into the house I'm remodeling which is in a better location, but no place in this town is especially good for car free folks.
