I think they just might be-be, even though that one looks awfully dark. (The empty coffee cups lend some credence to this theory.) Altogether there were four liquid-filled ziplocs sitting here on the desolate sidewalk between Calvary Cemetery and the Long Island Expressway service road. I didn't have the guts to inspect the lumpy-looking contents of a plastic shopping bag sitting next to one of the cups.
Huh. I find plastic water bottles filled with pee on my perambulations around L.A.–but never a ziplock bag!
Takes some sort of skill to pee into a zip lock bag without getting it everywhere I would think.
But why?
