I agree. I lived in West LA for a few years and noticed that I was just walking around a lot more than in previous locations. I measured it to be typically 5 to 10 miles per day (I don't recall the number of steps but I recall getting close to 30k/day on some days). And I wasn't going out of my way to go walking --- it just happened because I walked to work, to get groceries, to visit friends, to go to the movies, etc. To me, the best long-term answer is also to change the environment to be more amenable to walking.
