This is a clear reminder to keep your eyes on the ground when walking in Rattlesnake country.
"All the animals of the earth, all the birds of the sky, all the small animals that scurry along the ground,
and all the fish in the sea will look on you with fear and terror. I have placed them in your power.
I have given them to you for food, just as I have given you grain and vegetables. "
Genesis 9:2-3
