If you are going to try to catch them over some type of feed at random, try some soured grain. They can smell it from a distance and will come to it whereas they would have to most likely stumble across the corn in the dark to stop and eat. You can use a regular beam as well with no filter lens, as soon as you see one though turn the light out and get ready to shoot, and as soon as you are ready to find them in your sights, scope, etc. turn the light back on and shoot quick. Also, if you prefer and have a place to do it on PRIVATE property you can drive around with your light. Food plots and large grain fields are a great place to find them, but be sure to do like I said above when you see one. Lights off quick and only back on when you are ready. BTW If you plan to be out at night with a light be sure and let your local game warden know what you are up to. Good luck
