I am a happy hacker. I count off the days till I will be back on the mare and living the dream.
You are right that hacking is higher risk than being in the school. My first hacks on the mare, I kept contact, and leg on, just as you would like this lady to do.
But then one sunny day, I lengthened the rein and the mare was ever so happy. She looked around her at everything, the view, the people, the birds. If I lift the reins, she trots, if I say, Yes Canter, she canters. If she sees something that worries her, she stops and asks me to look. A long rein and ambling along does not mean there is no on-going communication between horse and rider. '
Sometimes the horses that look easy or look not to be being ridden well are the ones we have taught well and are just doing their job which in her case is to go safely on and make me happy.
