For the past three years, despite the fact that I do have a car, I have been taking the bus to work in downtown Pittsburgh. I only live about 4 miles from work, but when I take the bus, it still takes about 45 minutes to get there due to all the stopping. One summer I decided to walk the 4 miles home from work, and realized, not only is it good for me, but it was so nice to have a long walk, and it only took an hour and ten minutes. Hardly longer than the bus! Now, I walk home from work often in the summertime, and ride the bus otherwise. I have also been inspired and walk pretty much everywhere - out to eat, to the park, to shop, to the doctor's office, the grocery store, even if I have to lug two big reusable bags back that seem to weigh fifty pounds... day or night, I'm walking!
