When I first rode my bike around east Baltimore after moving to town 13-odd years ago, I often rode through the Perkins Homes public housing development. I wondered to myself why the city let public housing and the people who live in public housing live so close to the ritzy neighborhoods of Harbor East and Fells Point. and here we are, and Perkins Homes is gone, being rebuilt like this. It is like being in a whole new place I barely recognize, and I also know that once it’s finished, it will feel like it has always been here. Because we get used to things, for good or ill.
