StanM,
I have exactly the same question right now. I'm contemplating an elk hunt near Grants Pass, OR this year. Since I have to be in Denver for 4 days I'm thinking about flying to Denver, then to Medford, OR and then back home to KY. This will save me 4,600- 5,000 miles of driving. I'm thinking a Rooselvelt is going to yield 250 pounds of processed and frozen elk vensison. I'm pretty sure I've heard the airlines don't like dry ice in their holds. However, if frozen solid I'm not concerned about thawing on a 10-12 hour day. I am concerned about the cost though.
