And test your stand. Last time I used one of my hanging stands it let go on me and down we went but I got up and walk away without a scratch because I was testing the stand and wearing a harness.
Before you settle in go through your motions. Sit down, stand up, turn to the sides, draw your bow.
I know the haste can build when you are trying to get settled in before sun up but a spooked deer is better than a broken neck. The deer will come back...you can't unparalyze yourself.
