Apparently during trash pickup a week or so ago, the trash guys managed to spill a box of styrofoam (or some equivalent) packing stuff all over the road and in several yards. It's been snowy, and the beads have been buried until the melt this week, and now I've got hundreds of marble-sized white things all through my yard. They're squishy and round and definitely not the kind that melt in water. Is there any reasonable way to remove them en masse if they're too small for a rake and too soggy for a vacuum?
