Wind. Some stand locations only get hunted once or twice each season waiting on the perfect wind direction.
Entry and egress routes must compliment the wind direction. Always enter from downwind, never cross the area you expect the deer to travel. Use cover scent.
Multiple stand locations for each wind direction.
Avoid the people. Big deer won't tolerate pressure, neither should you.
Deer move locations as season progresses.
Food and pressure will affect where they hang. Cameras can help understand that. Also the time of activity, morning/evening activity can help plan your high percentage hunt time.
Now is the time of year to scout deer sign. Select stand locations and trim shooting lanes now. Maybe find a shed.
Shoot, shoot, study your weapon and be knowledgeable of ballistics. Be very competent is your ability to hit without doubt.
Be quiet in the woods.
