Hugely enjoyable morning's ride practicing "flying changes", which is when a horse changes leads at the canter or gallop without transitioning down to a trot. All very equestrian and, for me, a lot of fun, helped in part by Wilhelm Museler's book, Riding Logic. There's an awful lot to take in but Museler's Teutonic precision is softened by his occasional romanticism. Here's an example, in which the author warns us not to jump horses too young:
"...their legs are tired and they just do not want to jump. These are truly sad creatures, the ones who are victims in their adolescence to man's unthinking vanity and selfishness!"
Again:
"...it must be treated with tolerance or one will turn it into something worse than a dead machine."
So, treat the horses right.
Cheers,
