RE: Game cooling trick
I can relate to these antelope stories. 3 of us went on a winter hunt outside of Craig, Colorado. We got 3 goats & spent the night in the RV. It got COLD----the beer froze in the front seat of the RV. Anyway we put the 3 goats in my CJ-7 & I drove to Glenwood Sprgs, the next day. It was so cold the defroster could not keep up & I had to hand scrap the interior of the windshield. But after a couple hours of the heat & those antelope------well, to this day antelope makes me GAG. I can't eat them------my wife loves it----so at least I can still hunt them.
Fall hunt we would debone the meat & then put it in coolers with block of ice & also a couple pounds of dry ice. Seemed to work. As far as capes , I would wrap up a piece of dry ice in a bag & place inside the cape. But as soon as I got home it went to the taxidermist or into the freezer.
