Wolves don't eat carrion as far as I'm aware, so you would be not helping the wolves if that's your goal. Perhaps taking long night-time walks in the forest would be go down better? As for the bridge idea, I think the officers in charge of silt removal would not appreciate your legacy either.

I think cemeteries perform a rather useful function which is closer to waste disposal than ritual - the ritual is to soften the blow of that impersonal, utilitarian attitude to death.
