So..... Danny can hold the right lead canter, even when doing some mild shallow serpentines, IF I turn my seat to the inside. Duh... I can try to put my outside leg back all I want but it does no good when my shoulders and seat are twisted. But apparently by turning my shoulders in slightly, it positions my body to help him hold the right lead. Or NOT ask for the left. ;) It also helps if I put my big toe into his girth.
yay! Good baby horse
