Does anyone know what the best way to get the hide back to Seattle would be? (Freeze it in AK and bring it on the plane? ship it?)
Did you read the Field Care guide on skinning Bears for Mounts and Rugs? Specificly the last parts about Skinning, Field Care, Freezing, and Salting?
http://hunting-washington.com/smf/index.php/topic,9441.0.htmlTo answer your question about getting your hide home.
How long is your trip? Are you coming out as soon as you kill a bear or are you hoping for multiple animals? If your guide is proficient at salting than I say salt the hide. That is removing the skull and paws. Along with splitting the lips, ears, nose, eyes and removing the meat and fat on the hide. Salt has to be on the skin in order to work properly. If he is salting over chunks or meat and fat than he is wasting his time and it's not doing anything for the hide.
If you will have acess to a freezer shortly after killing the Bear, will you have time to freeze it? If you remove the skull / paws and fold the hide it may take 2 days for the hide to freeze solid.
I would bring the hide back with you when you come on the plane.
