Yeah, we use baling twine (incase they pull back and we can't untie them fast enough, they break the baling twine), and quick release knots, on trail and elsewhere, since our instructor is a safety freak... She doesn't let her students put a wrist loop around their hand when using that type of crop because once she saw someone riding with it and they fell off and broke their wrist... Also very strict about rolling up stirrups, etc.
