I hang mine in the garage by the hind legs. If its too warm it just means that you have to cut it sooner.
All you need is a good knife of sufficiant length. I use an 8" boning knife. A good sturdy table, butcher wrap, plastic wrap, some tape and bags for the scrap. I have 2 left to cut in my garage.... if you like maybe I can recruit the help of friends and photo the whole process?
