What exactly is the point of this? I don't need to use a crop on any of my horses, but when my last instructor asked me to carry one, I had much better things to do than argue with her. There is no harm in carrying a crop so why fuss over it? My dad had a saying when I was growing up that haunts me to this day, "in another 10 years, you will forget all about it, so why bother worrying about it now". Carry the crop, get over yourself, and enjoy the ride! It is not hurting anyone, so when you are riding under someone else, you follow their rules.
