Almont and the rest, thanks for the great info.
I hunt about an 1 1/2 hours one way to the closest locker and about 1 hour from a place that sells ice so I try not to go unless I have to. It seems every other year we get a warm spell that causes trouble.
I don't gut anything anymore, as soon as it hits the ground it gets skinned and quartered then the back straps and other loose meat is removed. After everything is off I open up the diaphragm to release a little pressure so I can cut along the spine into the cavity and retrieve the tenderloins (its now called the gutless method by the cool kids). All meat is put in game bags and if the weather permits hung from a meat pole in the shade. I have a tarp if I need to roof the meat pole to keep water off the meat. There is a decent Black Bear population in the area so I need to keep the meat up. Sometimes shade can be a problem as the area has heavy bark beetle kill so its hard to find a place that's in constant shade.
Sounds like my best option is a cheap chest freezer and I just run the genny when needed, like I say some years we bring home frozen blocks of meat and some years we catch a tan.
