I am thinking of doing my first archery antelope hunt. I am thinking of using a Double Bull blind on a waterhole. In your experience, how long after setting up a blind on a waterhole, can you begin to hunt it effectively? Will the better bucks avoid coming in the first few days? Should I set the blind up in the dark? I am not totally sure of the water situation where I will be hunting, but I have been told there are only a couple tanks the lopes can hit.
