I did the open with my mare Bally a few years ago. It was mainly over the BE Novice course. My team members rode at Novice anyway, but little old me hadnt.
It was of a time when the water was a palisade drop into water jump out over a palisade - unfortunately hit the palisade going in and ponio rocketed me straight over her head into the water
and pony only just missed jumping on me, annoying when only 3 fences from home.
