you don't have to use bait. the best place i have found is scrapes or rubs. if it is too late in the season (past rut), find well used deer trails and angle the camera down the trail. keep in mind that if you have a cheaper trail camera with a slow shutter speed, you'll have to find a place where deer stop or angle down the trail as i already said. if you don't, all you will get is the hind quarters of the deer as they walk by.
