The temperature reached 50 + degrees here in Chelmsford, causing the slick driveway to start melting way.  Hallelujah! My son was finally able to pry the frozen garage door open so we can get to the metal shovels.  We also got out the sledge hammer and pic axe and bashed the thick ice on the driveway, then shoveled the chucks and slush to the reluctantly shrinking snow banks.  So now the walk to the car every morning should prove to be much safer.
