I saddled Blue and ponied Libby for 45 minutes today. Blue didn't like it much, but we managed. Look at all the sweat on him! Hard work for him, leading a sometimes-protesting kid around. Actually, Libby did great, all things considered. When Blue got into his head-nodding gait, I noticed Libby's head was nodding too; in other words, she was doing her gait.
My worst problem with the whole exercise was the two boarded horses: They'd wait until we were some distance away, then come running, bucking and kicking past us. This was a bit unsettling for the filly; I think she felt she ought to join them.
Next time, I think I'll shut those other two horses in the lot, so my horses and I can work in peace.
