Some of the best hours in Dorr Township belong to nobody: two in the morning, snow falling straight down through the bur oaks, the county roads a blank page. That is when FJR Tree Inc is working, pushing back drives, opening walkways, salting the spots at the bottom of a slope that glaze over first. Out here the fields give the wind a long run, so a lot cleared at midnight can need a second pass by six, and it gets one. The reward is small and complete: a door opening onto a path that is already there. Snow removal for Dorr and the towns around it, storm after storm.
