i think if I lived in an urban center I would do the same thing as you. Even now, we recently went from being a 2 car family to a 1 car family, with 1 VERY OLD car at that. Our car is too old to make long trips anymore, has no heat or AC, etc. but I was surprised to learn how inexpensive it is to rent a car. We are taking a trip to New Orleans in April, and rented a full size car for only $20 a day. We bike to work, but then use our car on the weekend to drive out to the country for our club bike rides. I used to work in Woods Hole every summer, and for about 10 years we'd live car free in the summer. Its great when the weather is great, but it is tough when its raining a lot, or if someone is sick or injured.
