RE: What is the biggest problem you face?
Shooting accurately with my recurve.
I've hunted all my life, and while I'm still learning, I can go into the woods and be pretty good at locating the right place to put the stand, how to place it, how to hunt it etc etc.
I think for most guys stand PLACEMENT is most critical. Not only WHERE the deer will be, but in such a position as to draw and shoot without them seeing you.
