RE: sizing your deer
We don't shoot anything less then 20"+ with mass until late season in Jan. After that kill what you want. There are plenty of them on every hunt. I prefer the yearlings though. They are lighter and quicker to deal with.
However after I saw a friend skin, grab de-boned hind qtrs and back straps, in less then 15 mins speed isn't an issue. He dosen't even bother to gut the deer.
