Elmer, OK 5, 16, 15 Strong Tornado

A significant tornado developed along the red river and crossed less than 1, 2 mile to my south, a semi is shown driving south apparently toward the tornado in the first shot, multiple vortices can be noted throughout. Large hail then began falling forcing me to seek shelter momentarily. Following a hook slice the tornado once again became visible, I managed to approach it within several hundred yards as power poles were snapped and trees thrown.
