I used to have an office near Folsom California and our lab building was a large double wide office trailer with concrete steps and wrought iron railing. Every morning (before all the lab techs who were from India or Pakistan) I would go a unravel the little baby rattlesnakes from around the rought iron railing. They would curl up on the warming metal so they cpuld get their body temps up as the sun rose and warmed everything by radiation.
Some days Id have little box full of maybe 5 or 6 little rattlers and Id take em to the ranger of the AFB where we were located near. (We were mining gold from the old pressure washed sands from past gold mining.
The snakes were just as cute as that one on the opening shot. If you held em, thyed just stay and warm themse;ves on your hand. But dont ever put a finger near em. They can nail you just like an adult.
PS, black snakes (Im assuming thats what the little guy ws) are often mean little pricks. I got bitten right in that flap of skin tween your thumb an forerfinger and he just hung there biting you like a Maine blood worm.
