This one time, at band camp...
Ok it wasn't band camp, it was out back, but anyway,
I remember the image in my mind:
a big doe at a surveyed 208 yards (I am a surveyor - so I checked it out later) and I put one high in the boiler room, and she literally stiffened up - like she was frozen, and held that pose for what seemed like an eternity, although I knew it was only 4.476 seconds.
Then she fell over.
And right there, I remember what my health instructor said in high school.
"Always remember, son. Speed Kills"
true story.
