The bug/minnow/fish/bigger fish thing is pure myth. I have been night fishing with floating lights then submersibles since the 70's. Keep the light on or below the water. Bug protein just isn't tasty. As far as location.................main lake points, points, points with one 15# anchor when it is calm and two when it is breezy. 25-35 FOW. Jigs are just as good and probably better than minnows. Go to the bottom and reel up one turn. Jig 5 or 6 times. Reel up a turn jig 5 or 6 times. Repeat until about half way to surface. Back to bottom and repeat. I won't take long to zero in on them. Keep in mind, that as the night goes on they will gradually move toward the surface. If you aren't getting bit, adjust depth. That goes for minnows or jigs. As far as I am concerned, there is no better way to teach someone to jig fish than to take them out at night. They will learn to live for the THUMP! This is as good as it gets where fishing is concerned.
