I'm really excited about it.
I was going to go anyway, just for some alone time, but decided that Becky should go too.
She'll be 8 this September, so she's old enough to understand that you ~can~ hurt a horse. I won't have to be concerned about her pulling back too hard on the reins or kicking the horse to go faster when she isn't ready to ride full canter yet.
In other words, a mostly worry-free ride.
Most important is that she's old enough at 8 to grasp the somewhat complex combination of position and cues to communicate with the horse, and understand the feedback she gets. At six, it's too much. At 8, she's much more coordinated.
