We have a car that my husband drives to work and we use to drive to LA once a week, so we aren't car-free. I am working on getting the things I need to be car-free (lights for my bikes, something to carry groceries in, etc.) and riding one of my bikes most everywhere I need to go.
In the running shoe store, they have books and I picked up a copy of Divorce Your Car! there last year. It really got me thinking about all the reasons one should consider being car-free. The reasons I chose in the poll were environmental and other, the other being how much fun it is to ride a bike.
I'm hoping over the next year or two that we can wean ourselves further and further off cars.
