This is a family of four that lives without a car. I haven't read the whole thing yet, but here's a choice quote:
People who don't ride or walk seem to think our way of getting around must be tiring or draining. The truth is that we need both stress and rest to build strength and stamina. A life of ease, where your only effort is clicking a mouse or pressing a gas pedal, will lead you to a place where every effort is draining, every step a struggle.
