RE: Dragging the deer out
I think all these gadgets are just that... gadgets; and for the average hunter are not needed. Just grab the deer by the anters and drag him out. I've dragged fairly decent sized bucks a good distance before using this method.
Larry Benoit once said, "The tough part is finding a big buck. The easy part is dragging him out." or something like that. CI could probably correct me if I misquoted Larry.
Good luck.
