There's no doubt that deer see amazingly well in the dark. When it gets dark, before climbing down from your stand, there's a false feeling of security on our part. Because there is no light, we feel there's a better chance we might not be seen, because we can't see for ourselves. In reality weCAN be seen plain as day.

I'm facinated with how a large buck with a huge antler spread can run full bore through a thick cedar swamp in the dark with no moonand never get hung up, caught up, or even smash into a tree.(I know it happens occasionally, but they disappear so fast through the timber you would never know it)

That's amazing!
