The fact is that every time you go fishing, you are in the dark. You can't see what's under the surface. You see a bobber. You see a top water lure. You see the end of your line when you're dragging a submerged lure or any other kind of bait. When you limb line or straight line, you put the bait in the water and hope for the best. You're fishing in the dark.
Why is there a difference as to whether or not the sun is shining? Fish bite at night and during the day. Night fishing is fun with a bucket of chicken and a six pack, not to mention a good fire to sit next to while telling your lies to your buddies. I drug a sixty-five pound flathead out of the water down in Kentucky with a couple of "good old boys" one night a long time ago using a six inch bluegill for bait. So what?
Fishing is something you do because you want to. Your success will be determined by your persistence. I have persisted for a long time and have managed to feed myself and many others for an inordinate number of years. God will stop me at some point and that will be okay too. I'll be dead.
