Umm...I'm pretty sure that Deer is very much alive and shouldn't be in the truck of a car. Even if it was dead...I just don't think that is very sanitary to have a deer in your truck or humane.
Here is the video of a Michigan man who 'thought' the deer he hit was dead...and he wanted to take it home to eat it.
But wait...didn't this happen before? I mean, in the movie Tommy Boy?!
Yes I thought so..
Note to self and everyone else:
Never put a deer in your car...dead or alive. Maybe on the roof or in the back of your truck, but please make sure its dead!
