Wow, you make it seem so complicated. As an old foxhunter myself I figure that if the horse and I are still alive on the other side of the fence, it was a good jump!
Just kidding. That was a good explanation for her.
Reader's Digest Condensed Version: "SIT BACK AND HANG ON!"
Guess I've been spending too much time at hunter shows . . . they like a little polish. But, seriously, the biggest compliment I have gotten in a long time was from a non-riding mom who was standing outside the ring during a jumping class. She pointed to my mare and me going around and said to somebody, "The rider doesn't look like she's moving at all." The person standing next to her said, "That's the point!"
Of course, the fact that my mare canters smooth as silk and jumps out of her stride means that I don't HAVE to move.
