I tied Speedy in a new spot and asked him to kindly keep his marbles in his head. I hopped aboard Izzy and set off. As soon as were were clear of the mounting block, I did a quick check, asking him for a turn on the forehand. Oh, my! Was he ever quick to respond.
From there we moved on to the trot, but unlike a lot of days, I was able to use the whole arena right away. For the month leading up to our last lesson, the one in early February, Izzy just got more and more rideable. I could put him anywhere I wanted at the speed I wanted, which was not the mach 10 he prefers. During the lesson, he was a raging lunatic, and for two rides after that the behavior continued.
The butt-kicking seems to have got him back on track. On Sunday, I was able to leg yield off the rail and back again. Speedy helped with that as he was tied right in the middle of the long side. Izzy was being so adjustable that I was even able to do the same thing at the canter. We didn't get quite as deep as needed for the shallow loop at First, Test 3, but we weren't too far off either.
His future self is worth the wait. In the meantime, I see a lot more turns on the forehand in his immediate future!
