“Necessity is the mother of invention.”
I don’t claim to have invented round pens, however being a professional natural horsemanship trainer (www.naturalbridges.ie) from California, living in Ireland, I certainly have a need for one.
After researching my options, I was just not happy with what was available. Most options were too labour intensive, expensive, or not purpose built for the equestrian market (ie. for sheep or cattle).
Being involved with horses for the last 30 years, I have some very specific needs and wants in a round pen (sometimes called bullpen or lunging ring). With extensive experience with American round pens, I have begun manufacturing American style round pen panels (called pipe panel in America), with very specific features that highlight horse safety and ease of use.
