I was hiking in central Florida and came across an Eastern Diamondback that was around 7 ft long. It coiled up and made a heck of a racket. I watched it from a safe distance. Even though I knew it could only strike 2-3 ft I kept about a 10 ft distance. It was really angry at me being there!
Close calc: snakes’ strike range is 2/3 of length so the 7fter could have gone 5ft strike. Question is how fast can they set up coil for second strike another 5ft away :)
