Watching for broadheads in deer is something that is a good idea to always be on the look out for, I have heard through the years of several people finding broadheads in deer they shot with rifles. The muscle & fat of the deer just grew around the broadhead. As far as in the dark, a good flashlight should be a part of everyones bow gear. I prefer the mini-mag light. There are too many movement shooters out there to be bumping around in the dark while going and coming from stands, its a good idea to always use a light or glowstick when coming and going to your stand in darkness.
