In reference to mstrooperwife--I think that is why up here in the north we hang the deer for a few days before butchering-weather permitting. has to be cold!
 
The longer you can hang it, the better it is. if it is cold enough, some guys hang them for days. sounds gross, but what do you think they do with beef? it is better aged I believe.  
Also have heard of soaking it in milk too.
