A pothole machine that New Milford purchased last Spring has since filled over 20,000 potholes.  Mayor Pete Bass says the town has saved tax payer dollars by reducing the personnel needed to fill a pothole from between 2 to 4 crews of at least 4 men per crew, to just one person in the pothole machine.   Bass says the "coldpatch" that New Milford was using would leave the pothole shortly after it was put in the  hole.    He noted that this machine's application lasts much longer, cutting down on filling redundant potholes saving time and material.
