On Amazon USA there has been for many years The Road Kill Cookbook
and of course The Road Kill Colouring Book
I have often wondered about picking up carcases of pheasant duck and
Rabbit
etc.I did stop and size up a deer which had just been killed (they would all have to have been killed in my sight) but it would have ruined the interior!
It does seem such a waste, but if placed on the verge I would expect a lot of foxes, buzzards,and others to benefit rather than let it be ground into the tarmac
