You and your buddy set up on the downwind edge of a field where they are feeding at night and have a good 12 V battery and a strong spotlight. Have your AR-15 or AR-10 rigged up with a real good suppressor and presto - a freezer full of venison! LOL Joking of course.
But to do it legally find out where they are feeding and set up a little closer to their bedding areas about every 3 days or so. Just don't get too close to spook them. Or wait for the rut and hunt all day. That's about the only time a good buck MAY let his guard down. He only has one thing on his mind and it isn't eating.
