Shank, I put in the slow cooker for around 5 hours, then strip the meat with a fork (like you would with pulled pork) mix with bbq sauce and put it in a bap with caramelised onions.
The skirt, I never save it in deer, but the easiest way, separate the eosophagus from the rear of the windpipe, break all the connective tissue into the chest cavity, into the guts, gently release the stomach and start pulling, the feed tube should pull through, empty the guts etc out of the deer and then you can see the undamaged skirt.
I do buy beef skirt, it is fantastic in pasties!
Cheers
