Alway hung'em from the rear legs, for many reasons. It's much easier when you have the rear legs spread apart, how would you get to the organs properly if it were hung from the neck, second you want to start from the anus and genitals to get the pee bladder and stool out of there, thats the starting point of gutting, you have to spilt the rear and bring the intestines down, I cant see how you could possibly start from the neck and go down. You need to teach your friends the proper way.
