I scored a 9. I live on the same street as the town hall and the police and fire departments. The post office is just over a mile away, but you can't walk there (well, I'm sure you could, but there are no sidewalks and it's along a very busy road). The nearest grocery store is probably only 5 miles away, but along the same very busy road. There's pretty much nothing else in my town.
My college scores a 57, which is quite ridiculous for the students because literally everything you need is right on campus. You can definitely walk to wherever you need to go. Although, I guess if you wanted groceries, it'd be quite a walk to the nearest one.
