While I live in a city its spread out. We don't have neighborhood anything. Each neighborhood is basically a small city or town itself. If you didn't have a car here you would be out of luck. Mass transit sucks here.

Keeping 15-25 gallons of fuels isn't too difficult. 15 gallons in a garage is not an issue. Fuel stabilizers have come a long way.

Simply keeping no less than 1/2 tank goes a long way and 3/4 tank if you have a high capacity tank like mine.
