A most disgusting sight. I phoned it into 311 and was switched around. Bottom line after being asked whether there was still flesh on it and might it be a rat (it's not): it is apparently not the Dept. of Sanitation or other city responsibility because it is considered private property. It looks like it was dumped there rolled into and/or covered by a tarp that got blown away with wind. Any ideas as to what can be done about this other than my going to have to shovel it up myself (I'm not)?
