[MeneMeneTekelUpharsin]

Russells Viper is the snake known by Viet Vets as the "2 step" or "3 step." It's a much larger snake.

The Thais call the banded Krait the "two-step snake" and rightly so. If you take two steps after being bitten, quite often by then you were dead. My father killed one in the front yard after a monsoon rain saw it swimming by. Very scary incident. Deadly snake, no ifs, ands or buts.
