Another display at the horse fair in Texcoco, Mexico was offered by the Women's Mounted Police unit. Take a close look at their saddles! Although they are designed to be ridden sidesaddle, they also have a stirrup on the off side, allowing the rider to swing a leg over and ride astride. In the last picture you can see that the first rider in line is riding astride, while the rest are riding aside.
This group did a lovely drill-team performance, and also gave lots of rides to children from the audience. The kids were handed over the railing by their parents, and perched on the rumps of the horses for a spin around the arena, before being handed back again.
