Niagara Falls Boulevard wakes up early — coffee, hardware, the plazas switching their lights on while the sky is still the color of slate. TCB Lawn & Snow is out ahead of all that, plowing lots and driveways, shoveling walks and entryways, spreading salt on the aprons where traffic packs snow into ice. A cleared lot at six is the difference between an open day and a closed one. Storms in Amherst arrive in waves, so the route runs and then runs again. Taking care of business, in the most literal sense of the phrase.
