Check regs to see if it's legal in your area. I know up in AK you are required to leave the meat on the bone. They say it causes want and waste along with slowing the cooling process down due to large quantities of meat tossed in one bag.

This is not a law in all GMU's in Alaska...they recommend it to preserve more meat but it is not required legally all over. When we hunted black tail on Kodiak Island we boned out every one, but if we went up north to the Koyukuk area to hunt moose, that area requires the entire moose be carried out on the bone except for the hide. They check you at a river check station on your way out. When boning out an animal we always ensured we wasted no meat.
The "law" you referenced states that every piece of edible meat must be salvaged. Which is what we did every time.
I agree it was some what easier to leave the moose on the bone, but we had chainsaws helping us

. Boning out the deer is a huge help when you are 7 miles from the tent.
