I have had deer meat both ways from hanging for days back when my dad hunted Pa and there was snow on the ground most of the winter.He grew up on a farm and believed in hanging deer like beef.Personally I have not seen a big difference in taste at all maybe because here in Pa the majority of deer shot are young deer.If I was to shoot a buck 7 or 8 yrs old I might think about hanging it if possible then I am dreaming anyway.
