I still live in urban Greater Seattle, although not in the steel and glass neighborhood of my first eight years. Now my neighbors have yards, and driveways. Someone nearby has chickens in a wire pen out front; she lets them loose to forage on the grassy strip between the sidewalk and street and goes back in the house. There they stay, oddly enough, and apparently they return to the enclosure without protest when she comes back outside and calls them in. I don’t know if those chickens are very smart and realize that they have a good deal, or very dumb and oblivious to the fact that when outside the fence they could go anywhere they want.
Another neighbor is growing pumpkins in the front yard, fitting the definition of “urban farmer”.
I have no aspirations myself for either chickens or traveling vines that fill the front yard with the promise of Halloween. But I’m glad my neighbors do, as it makes my daily walk to the gym more interesting.
