There is nothing more frustrating than equipment gone astray. I always provided a complete equestrian first aid kit- often the only kit at the various ranches I've boarded or worked at. I let it be known it was for emergencies, and my only request that supplies so used be replaced. Well it happened; my own horse was injured and I stared into a half empty kit recently raided. I recovered most of my supplies later, including a special halter. The horse attached I considered my property until the owner paid a rental fee.
