For the guys relying on the ice and small cooler year after year, or bits cut up & in the 'fridge, might I suggest building a small closet sized (4'X4' would be plenty big enough) hut in the backyard and hooking in a small portable airconditioner. Well insulated with styrofoam it'll keep your deer cool enough for a week or so, and it won't skyrocket your electrical bill 'cause you plug it in only when you need it.
