Even though Cambridge is a big city, there are little places all over the area that have a rural quality. Usually these places are the gardens or environs of old wood houses. I lived in such a place from 1978 to 1988, and it had enough land for an urban garden where I grew tomatoes and green beans. You needed a fence to protect your garden against marauding people, though I don't think this picket wood fence is intended to protect anything. I loved finding these bits of the country in the city and drawing them. There are places like this in a lot of cities, including my own in the suburban DC-area but drawing is more difficult because residents are suspicious of someone who parks themselves on their street for no apparent reason.
