More than 80 city sanitation trucks will be used at intersections and other strategic spots along the 2 ½ mile parade route to create an imposing physical barrier to terror. The trucks weigh about 16 tons empty and up to twice that with sand. "You can ram a New York City Sanitation Department sand truck with a lot of things, but you're not going to move it," said John Miller, the New York Police Department's top counterterrorism official.
