Figure out how much extra it's going to cost you to ship the meat/horns back via the airline, then figure out if it's cheaper to just drive out there and back. I don't like the hassle of checking guns/dogs/kids/meat in the airport so I just drive. I can make it from Raliegh, NC to Salida, CO (2100 miles) in about 22hrs driving traveling with a 5yo and a Lab. I make sure the meat's frozen hard, pack it in the coolers and throw some dry ice on top. Only had some thaw on me once (I don't think it was frozen good to start with), but we ate it as soon as I got home so it wasn't wasted.

My fuel bill round-trip is $4-600 depending on fuel prices at the time. And I sleep in the truck at rest areas so I don't have to pay for a hotel.
