Well, let me put it to you this way maddiedog, I had plenty of light, and probably could have bagged another limit after the 5:00 daily closure time, which in my mind really sucks, but oh well, that's what our regulators call sundown. I literally had mallards sitting on water not 10 feet away at 5:10 and later, and could identify them with no problem. I think they need to move the sundown hour out at least 30 to 45 minuates. You must be north of me, we have lots of ice, but most of our boat launches are still open, should use a 4x4 though because the pull outs are really icy, when I put the boat in on Friday, I literally slid into the water, that was really spooky but got r done........good huntin!!
