Some homes

 I was walking through an area with many very nice homes. I wonder where all the money came from, both for the buildings and grounds but also for the upkeep.

This is a very narrow road with two-way traffic, which must involve a lot of backing up since the road is not wide enough for two cars to pass, maybe two motorcycles but not two automobiles. All the homes here have walls separating them from the street. I am tall enough to see over the walls without being too obvious about it. Behind the walls are large old houses with Japanese style gardens in front of them.
