On a February afternoon, the streets are deserted. You can see a skyway in the distance. You are looking north, from within a skyway, over the void between the glass capilliaries carrying little human cells from organ to organ within the austere stone body of the city.
Skyways have been criticized for absorbing the life from the streets into themselves, as though they had some kind of inhuman, selfish motive. But this is the fact of a Minneapolis street in February. If people weren't moving in the skyways, they wouldn't move at all.
