I think I need to elaborate / clarify my earlier words:
---
For comparison, my family lives in a "suburb" 20 minutes or more away from everything (and 25 miles / 40 minutes from the nearest Walmart). When I was in San Francisco, I wouldn't have thought much of driving 30 minutes to Walmart (because of my background), except that SF doesn't exactly encourage, or even tolerate, car ownership.
Then again, I could (when I was in San Francisco) walk 10-15 minutes to Macy's, Nordstrom, or Target.

I'm not sure why you bring up Mountain View, as I didn't mention it and in fact was not referring to it in any capacity. My family lives in a "beach community" with one store, of which I do not know the name. Besides the store, there's a church, a school of some primary-or-kindergarten level, an outpost of the public library, and a fire department. I have also heard the location described as a "suburb". Going anywhere at all is a hassle; there is nothing nearby. It is possible, given the right wind, to smell the fertilizer that the local farms apply to their fields.
