Tosca, Yrsa and Lina all came from the same farm. Lina was sold and came to Applegate two or three years before our mares. She also moved from Oregon to Virginia and back in that time. Yet, when we pastured Lina and Tosca together, they acted as if they were old friends. They are also half sisters. It made me think of the studies regarding separated twins who grew up very much alike, although having never lived together. There seems to be some sort of genetic bond.
