When I was a kid, the Parish (county to the rest of America) dug a big drainage canal behind our home. They used some of the excavated dirt to backfill a small natural drainage.
They did it in February (as best I remember) disturbing a bunch of snakes and turtles. I found a very large, huge to a kid in the 4th or 5th grade, Cottonmouth. I shot it a couple of times with my .177 cal. Benjamin Pump. I got a shovel from home, and carried the snake back home to show my Dad that was busy tilling for our garden. It was all I could do to lift that snake.
When I got to my Dad, he pretty much freaked out, grabbed the shovel from me…..and cut off the snakes head, along with at least 6 or 8 additional inches of snake. At my insistence, my Dad measured the remaining snake…..4 ' 6", plus the part we didn't measure makes a pretty darn big Cottonmouth!
We never got a picture of the snake, which is second only to my disappointment of not getting a photo of my first deer just after turning 11 yo. memtb
