Yes, I have prayed many times on stand while hunting. I often feel closer to God while in the woods and watching the sunrise on a frosty fall morning. The beauty God has given us on those mornings are special times for me. I feel I am in the presence of the Lords most cherished cathedral. Kinda makes me feel sorry for
those who do not hunt and are missing out in Gods splendor.

No special prayer, I just reflect on my feelings and needs at the time.
