Shockingly tiny amount of the meat was un-usable.
I've found this to be the case many times. When I lived in town, there was a park in which the deer herd was tremendous. Speed limit around the park was 35mph. Two-three deer killed a week like clockwork.
Used to be on the 'roadkill' list and cut up enough deer to fill my freezer and most of my siblings freezer. Never kept a questionable piece of meat.
Law was happy, they didn't have to fool with it...I was happy cause I got the meat. If the deer did happen to be torn up to bad or wasn't fresh, LE wouldn't even call. They put carcass on the list to be picked up by the sanitation dept.
All worked out well.
