"Don't need to . . ." No, but two years ago I used a different processor (wife can't stand bloody kills on her kitchen table) that took forever to get the meat back to me. Two weeks go by and by now I'm pissed. Didn't know why they should take so long unless they lost them or just incompitant.
Found out they aged the deer for "10 - 14 days". Absolute best meat we've ever had and have and will age all game meat (in an old frig I bought) in the future.
Specifically with bear, it is important to cut off ALL fat from meat. Gives it that nasty/gamey/dogs won't eat it flavor.
