I've had two teenage boys, my adult daughter and a 10 year old grandaughter up on Tosca, always with me holding her for them to mount.
Since everyone is back in school (daughter teaches), today was my day. Tosca stood like an old broke horse while I mounted from a mounting block, stood still until I asked her to move off, than walked sedately around the round pen on a long rein. All alone, just the two of us in the morning sun. Life is good. Next time, the riding arena. Nancy
