I think she's just over 15 hands, but fairly stout, so she looks bigger. But Brennen isn't that tall. He's 11, but not one of the taller kids in his grade 6 class.
The kids were at my Mom's place that weekend. They had to leave her place at just after 5am to get to the clinic by 9:30, so by the days end, they were very tired. And Brenn is quite serious about his riding. I got after him about the legs. Until he saw the pics, he didn't realize what he was doing.
