Up on East Mountain the wind gets first say in every storm, and what falls as flakes downtown arrives here sideways. GBE Guifarro Tree Service takes the cold shift — plow lights sweeping a driveway at four in the morning, snow pushed clear to the banks, the buried steps found and shoveled so nobody has to guess where they are. There is a rhythm to a Waterbury storm night: run the route, come back around, stay ahead of what is still falling. When the sky finally empties and the sun climbs over the valley, the drives are open and the day can start on time. Snow removal, storm after storm, across the city and the towns beside it.
