The Gowanus blocks are brick, steel and open pavement — the kind of ground that ices first and thaws last. Adco Snow Removal reads a forecast the way other people read a schedule, and when the sky closes in over the canal the trucks are already loaded with salt. Lots get plowed and the piles stacked out of the way, loading docks and walkways shoveled down to the surface, ice broken up before anyone has to cross it. Work like that happens between midnight and daylight and is measured entirely by how ordinary the morning feels. Snow clearing and de-icing for Brooklyn and nearby neighborhoods.
