Years ago here in Vt deer drives were pretty common. Knowing the way game moves in a piece of woods as well as using the wind to your advantage makes a controlled slow drive productive. Many of the deer we used to get were actually killed by the pushers as the deer tried to sneak out the back door. If the drive is done quietly by experienced still hunters standing or walking deer are often the result. When on public land deer are often moved by one party or another. The difference between that and a slow drive is that everyone is aware of the placement of the other hunters on a drive.
