RE: Dead deer strapped to vehicles
Anything I kill and anyone else I know kills, they put it in visible sight for anyone who is willing to stare. I think it's fine to show off your trophy. Around here kids bring the trophys to school and show em off. I always like to see em. Elk season seems to be very "visible." If our hunting party kills a bull, it's head is sitting high in the back of the truck and the wang is usually hanging off an antenna. No one objects, everyone laughs. Seems fine to show a kill off in these parts.
