Most people at my farm do this and no one complains.
I try not to do it when people are riding, but I don’t mind at all if someone does it while I’m riding.
None of us at our farm (minus one or two people) are that “hardcore” that it would completely disrupt our ride.
Most of the time we are goofing around, trotting side by side or the like. Not many people are working on their half pass and pirouette maneuvers. :lol:
None of us would belong at a barn where non-rolling was the norm, so I agree that rolling is a cultural thing.
My horse wants to roll, he can roll to his heart’s content!
