May in Chicopee arrives all at once: the Chicopee River runs high with the last of the melt, the ballfields go from mud to green, and every lawn in town needs cutting the same week. Mayday Property Management takes that on for the properties in its care — mowing and trimming on a set rotation, edging walks and parking aprons, mulching, seeding thin ground, and clearing the yards out in spring and again in fall. Rental blocks and single houses alike look after themselves better when somebody keeps the grass honest. It's a good feeling to pull up to a building where the strip along the sidewalk is cut square and the beds are dark and even. Through the whole growing stretch, the routine holds.
