Of course horses spook just for fun and to see if
the rider is awake and aware. I have had some legit spooks. One was
the horse eating logging machine, and the other were the surprise horses coming
around the corner at us. At least my mare didn't spook at the semi that
greeted us on a 2 track. She leaped off the trail instead and took me with
her. All horses spook if something scares them. It behooves the
rider to be aware of his/her surroundings, and to be a fairly decent
rider. And remember, an arab's fourth gait is the spook!
