Little Man up, a little western fiddling around. Rode him up walk, trot, canter, english bit. Fooled with collection a little bit more, especially at the walk & trot. He was less than happy, but eventually compliant.
At the canter, I tried to break it up into spurts, mostly to keep his mind moving. Changed circle sizes, made unexpected turns, all trying to keep him from thinking "stay on the rail & go go go!"
Worked for probably 40 minutes or so - It was ridiculously hot, even for a late ride. Uncomfortably warm... and humid. YUCK.
