Less than two minutes: bus stop, pharmacy, dentist, 24 hour emergency medical
Less than five minutes: mailbox, dairy (convenience store), dry cleaners, chiropractor
Less than ten minutes: grocery store, hardware store, doctor, butcher, bakery, post office, bank/atm, community pool, takeaway food, video rental, bookstore
Less than twenty minutes: downtown, so pretty much anything else: retail shops, library, restaurants, cathedral
Remember, those are walking times (one way). In comparison, our place in Texas was in the middle of a big suburban block. Things you could walk to numbered about two:
Less than five minutes: mailbox
Less than twenty minutes: community pool
Furthermore, most of the year you wouldn't really want to walk very far outdoors in Texas since it's so hot. On the other hand, we didn't have a car at all here for just over four months, and survived perfectly well.
