Spring Glen sits in the middle of Hamden, a grid of porches and old street trees between Whitney Avenue and the Mill River, and in February it goes quiet under snow long before the plows find the side roads. Spring Glen Landscaper LLC works that ground, clearing snow so driveways, walks and entries open up again. It is plain work with an obvious result: a path to the car, a stoop you can stand on, a morning that starts on time. The route runs while the neighborhood is still dark and the streetlights stand ringed with falling snow. Snow removal, in Hamden and the towns nearest it.
