With all due respect....Y'all crazy.open the cavity and wash out with a hose. hang from the back legs. the water will get the cavity temps down. we have let them hang in 60 to 70 degree temps in a shed or in a non heated/cooled barn for up to 3 days. never had an issue with those temps.
you guys have obviously never been on a float trip or anything like it. what would you do if you were in alaska for example for 3 weeks and the temps were in the 70s for that time? say you killed a moose on the 2nd or 3rd day of a 21 day float trip. what are you going to do with the meat? been there done that and the meat ws fine. all you have to do is take the proper precautions first. hanging doesnt hurt the meat unless its cooking and not chilling.
Makes sense to me considering what our ancestors did before refrigeration.
