i had the same worry- as i was backpacking...when i boned out the meat, i had to leave evidence of sex(penis in this case)attached to "a significant piece of carcass", according to my local dow guy. it was my first elk(big game period for me)and i figured out how to do it- ugly but servicible...its harder to describe than it is to figure out. basically, cut(or hack, in my case) around his unit leaving it attched to leg muscle. pain in the butt really...
