I wonder if your horse and mine are
related? Mine does the same things, including the springy trot that throws
me out of the saddle. I've almost given up trying to post.
We did a slight variation on that today. My rotten horse was doing
that boingy, bounding show-off trot because a herd of horses ran up in their
pasture behind him. You know that trot that vaults you out of the saddle
every stride. Then I was laughing at the idiot and he darted sideways on
a road going toward home, then ducked his head because I was on his neck,
and I did a slow motion fall onto the gravel road. The spin part
comes in because I had a death grip on the reins and he was trying to get
away, and spun me in a big circle on the gravel. Luckily he finally
stopped :-D Amazingly I have not a scratch, just a bruise on my butt
where I hit the hardest I guess, and my tights and tee shirt are
unripped. There is a big doughnut in the road swept clean of gravel by
my skidding body :-D
