It happens but, you have to stay with it. Most of the time by now I have taken at least one if not two bucks. But I have been on 6 good hunts and I have not seen a deer from the stand yet this year. So what do I do, Well I "keep on keeping on" and don't get lazy about stuff like the wind, my scent, and stand placement and ect.
The Rut will be here before you know it and things will start to change so be ready and keep on Hunting. The moon is not real good right now for ealry morning, but it well change soon also.

good luck and Keep our head up.
