I really don't want to write this post - I'm a little superstitious and this post comes with a BIG knock on wood!
I honestly think my last fall was off Gracie (of course!). It was a couple of years ago and I was schooling her for Nat in the bottom paddock. A truck went past and she scooted and bolted. I tried pulling her up and she just put her head between her knees and bronc'ed out! I bailed (I almost always bail when I know I'm going to fall) and wasn't hurt thank heavens. I was SO CRANKY with her though. I got straight back on and set her to work!
Look at her - butter wouldn't melt in her mouth:
