If you’re looking for a new neighborhood, or just curious about your current one, browse around WalkScore. The algorithm is admittedly imperfect, but I learned some new things about my own neighborhood. For example, because it is technically in another city and seemingly attached to a school there, I rarely think of the park that WalkScore shows is actually closest to my house (2.5 blocks away). You might find some tips for saving gas, talking to neighbors and to generally make walking around healthier and safer for our families.
