I hunt California and its hot all the time. Like stated above start meat cool down asap. i have found that having an ice chest of ice can get expensive as we are not successful every trip so i carry an ice chest with a bunch of those refreezable ice bags or just a few frozen 1 liter Aquafina water bottles. If i get my hog i quarter or bone it out and throw it in the chest, if close to home i just head home and get it taken care of, if far from home i head to the nearest store for ice. This works well and saves on the cost of ice if i dont conect.
