Henhouse,
 
I personally do not carry my crossbow already drawn when I am walking to and getting into my stand.  Hard to explain unless you try it but I just do not like the feeling of carrying the thing over my shoulder locked back.
 
As to being able to draw it in a stand.  I use a rope cocker and it still requires considerable effort to draw mine back.  In most of my portable stands I would be somewhat leary of doing it but in some of our bigger permanent stands, no problem.  If one had a crank in the stock like some models do I would imagine one would be able to redraw without a problem.
 
And no, Pope and Young does not recognize crossbow kills in their record book.
 
As to the rest of your post, that is another discussion.

thats up to the hunter whether or not he wants to carry it cocked or not. It is legal to, although the crossbow manufactures say that you can have it cocked but recommend not placing bolt in it until you are stationary. You can****one in a treestand if you have enough room to sit the stirup on the base of the stand and enough room to bring your hands from your knees to your chest. If you have a crank it wouldnt be a problem to****it back in any stand you can fit the xbow and yourself in. As for getting a second shot, you have a better chance of reloading a compound to get a second shot. First off, the noise a xbow lets out when its shot will most likely send the deer high tailing it out of there, second the motion needed to set the xbow down, recock it, or crank it (i believe the average crank and xbow needs 40 cranks to fully****it), retrieve an arrow from the quiver, and reloading it, is a lot of motion and noise to go through unseen or unheard.
