Any town which has 10% or less of its population younger than 55, has no public transportation, and any place to buy goods at a reasonable price is just outside of a 3 hour walk one way. So called because you need a car to get anywhere fun, and cars burn gasoline, which means more $$$ for the oil companies.

The main advantage is low crime, if a bank gets robbed, a walker or cane would of been used as a deadly weapon.
