Thanks guys. Dancer was never out of control on that ride. The only thing she did wrong was paw the ground when she got a little impatient waiting for the other horses to complete an "obstacle."
I think what unnerved that lady was the fact that Dancer hadn't been ridden more than a few minutes at a time in several years. Our trainer friend had told everyone about that - not because she was worried, but that she was amazed at how well behaved Dancer was for not having been ridden in so long. (The trainer loves the way she moves for some reason. Dancer has a high stepping trot that is as smooth as butter - really looks unusual to me.)
Plain Old Dee, horses Dancer and Rain I believe in dragons, unicorns, good men and other mythical creatures!
