If I kill a deer in Ohio, my grandparents will either eat the meat or donate to families they know that really need it. I wish I could bring the meat back to Utah but I know how much it means to them and how much they enjoy having it. It means a lot more to me knowing that it's going to their benefit or a close friend of theirs that could really use the meat. My dad shot a buck out there a couple years ago that we got mounted with a local taxidermist. The plan was my grandpa would ship to us when it was done. Well he ended up hanging it on the wall until he could find the time to ship it, and 2 years later it's still hanging on his wall. He's never been a hunter but I think he really likes having it up there.
The only experience I have shipping meat was when I went fishing in Alaska several years ago and brought back a few hundred pounds of halibut. The meat was cut, vacuum packed and frozen into 12" blocks. We placed several cuts in cardboard boxes and duct taped them shut. This was 15+ years ago and the airlines didn't make any fuss over it. The meat was still very frozen when we got home.
