Its easy to nod off. Get up at 3:30 a.m. and be in the stand way before light. After doing this a few days it catches up with you. I have about 11 or 13 tree stands scattered throughout the forest here and some are quite comfortable where I can snooze and stay in the stand all day, but I have some others that you've really got to pay attention where your at, especially when drawing down and being aware of your foot placement on the stand.
I think we all nod off and try to fight it b/c we put so much into the hunt and come primetime at 8:30 a.m., the eyes get kinda heavy. Been there and done it.
