Mary Wanless of Ride With Your Mind warming up Bertie for a demo

26.9.14 : I had taken Bertie with me to teacher training, so other people on the course got to ride him as well. It was driving Mary nuts that no one could ride Bertie forward sufficiently with enough 'ping', So she decided to use him for the demo ride that she does on every teacher training course. This ispart of her warm up for the demo.
