Alex was on Sherah's oldest horse, Pecos, whom she's had since she was in third grade. It was funny to see Sherah riding Twister with his long-legged gait and then see Alex on Pecos, who short little legs only allowed him to take many short steps to try and catch up with Twister. Alex being about 6" taller than Sherah, meant his legs hung way down on Pecos, making it even funnier-looking! :)
