Some times I used to walk to a deer stand way back around 3 am so I could get settled in and not disturb anything. Normally I’d doze off until it began to get light.
One particular time, just after I got settled the sky began pulsating with greenish waves that intensified, then bright rays raced across the sky with brilliant reds and purples, yellow and green. It was so bright it lit up the ground.
I sat there watching for several hours. The predawn light edged them out eventually, followed by sunrise. About a half hour later I downed a nice 10 point whitetail.
