Here is the picture i am looking at
http://www.whitetails.com/deer_info/deer_anatomy.cfm
It looks like there is a lot of room and vitals in the v shaped area made by the scapula and shoulder. I could see how this would be a bad choice from a tree stand due to the scapula but if shooting from the ground then it looks like a pretty good shot if that's all you've got.
However, if the leg on the shooting side is back then what does the scapula do? I would like to see a picture with a deer in this position to see how much of the vitals the scapula covers up. I've drawn back on deer and they have spotted me in this position before. Anybody have a picture?
