Really I was miserable and looking for an excuse to go to bed. Lol. When I could no longer stand it anymore I took it out. The bone was still attached pretty well but I couldn't wait any longer to get a nap before work for fear of not getting any sleep at all. I wrapped it in a towel and tossed in the cooler. 3 hours later just before work I took it out and the bone pretty much ejected itself. Definitely works to continue the tenderization process. And, at 3 hours in the cooler, still too hot to touch.
