Park Slope residents are pointing to another casualty of the never-ending winter: dead Christmas trees, denied a proper burial. Since it started snowing and never stopped, the once-festive decorations are still strewn about Park Slope, reports DNAinfo, which counted about two dozen trees and other holiday detritus on neighborhood blocks. The Department of Sanitation said garbage collectors plan to pick up the trees, but can’t if they remain frozen to the sidewalks. “But they’re getting so gross that my dog ignores them now,” one resident said. That’s right, even peeing dogs are sick ofthem.
