There must just be something about those blue dog-turd baggies that magnetically attracts them to the sidewalks and grassy patches in New Westminster. It’s as though dog owners, once they’ve performed the ritual of turd-collection, are supernaturally forced to drop the bag at the nearest intersection, median, or stretch of sidewalk fronting a low-rise.
Just kidding; there’s no magic involved unless one considers being an asshole magical.
