I found the public works department.
They have a way to report dead animals for removal!
I reported it, gave address, described exactly where so they wouldn't have to hunt.
Ticket status 2 days later: CLOSED!
Road status: No animals removed.
.................... they just ... decided not to bother. They didn't even go out.
I'm about ready to call city hall and tell them I'm not giving them a damn nickel of tax money anymore, since the city isn't doing its damn job. They don't even do their own tax collection; it's done by the state, who gives the money to the localities that impose their own additional taxes.
