Road hunters are bold. I used to work with a guy who would tell you all about how to do it and not get caught. He had a car that had one of those middle seats that would fold down so you could access the trunk. His wife would drive and he would sit in the back. When they came up on a deer he wanted to shoot he would shoot out the back window throw the rifle in the back and get in the front seat. They would go home, wait a couple hours and then change vehicles. This time they would get in his truck and go pick up the deer. I don't know how many deer he killed this way but I am pretty sure it was a weekly thing for him.
