Very good link! We always age ours for a couple days but the link says 5-7 days. The worst venison I ever had was I shot a nice doe at college and had to butcher it on my doorstep in town where I was renting and froze it right on the spot. Gamiest venison I've ever eaten. I ate it, but I really like venison. NOBODY else would touch it.
I think aging it in the fridge would do the same thing as hanging it to age. I can't think why having the deer "boned" still would prevent it from aging properly.
I read an article one time, I think "Fur Fish and Game" about a guy that hangs his venison for up to a month until he gets a green film on the meat, that he then scrapes off and butchers. I don't know but that's too long and too much bacteria for me.
