RE: Pelvic Bone???
I never split it in the field either. I take a few rubber bands and throw them in my coat pocket they come in handy for all kinds of things while hunting. One of the things I do with them is after cutting around the annis and makeing sure its free I pull it out wrap a rubber band around and when I'm ready to pull the rest of the guts out it comes out nicely and with no spillage.
