"Cross rails o/f"
I'm looking at the prize list for my upcoming show and I'd just like some clarification on these:
34) Warm-up Cross rails- trot corners
35) Cross rails-trot corners
36) Cross rails-trot corners
37) Crossrail-trot corners- U/S
38) Warm-up Cross rails
39) Cross rails o/f
40) Cross rail o/f
41) Cross rails under saddle
I'm guessing that the U/S in the first division means under saddle. How is the "under saddle" class different from the other classes?
Also, what does o/f stand for?
And last but not least, warm-up is not judged, correct?
