RE: Driving a car to your hunt
I have a game tray I use for the back of my SUV. I typically cover the animals with a tarp as to not get any PETA recruits. If all you have is a car, no reason you couldn't get a receiver hitch added to your car and buy a game tray.
I went to college in Vermont for a while at a small liberal arts schools. The local paper once had a picture of a group of "deer" hunters who had come up to hunt from the NYC area. They had a successful hunt and tied their "deer" to the roof of a Mercedes sedan. The roof eventually started to bow from all the weight. I would pay good money to see that picture again and would loved to have asked the guys how they got their "deer" onto the roof.
It was a picture of a big Mercedes, roof bowed in from theweight of their "kill": A big black and white dairy cow.
