Re: Letting them lay up.............
I have never left one over night. On the few occassions my buddy or myslelf felt the need to let the deer sit awhile, we left the woods before tracking, only marking the start of the trail.
We head home, grab a bite to eat, a beer for my buddy, and coffee for me. Then we fill the thermos up and head out after approx. 4 hours. Has worked well for us. There have been times we were out tracking at 2-3 am.
Like D-man said use the ole colman lantern, the blood seems to show up brighter with that than with a flash light.
