Why would a young country girl ride with two horses?
Probably not a typical post, but I really need to know something. What would a girl of about 15, on a poor farm, at midday, be doing a short distance from the stables riding a horse and having another in tow. I'm writing a book and I have some ideas, but I don't want to sound like an idiot nor do I want good horse people to drop my book in the 2nd chapter because it doesn't make sense. I'm sure that happens all the time in film and literature and I don't want to be one of those. She ends up running into someone that needs help and she takes the 2nd horse and gives up the one she was riding to the stranger and takes them out of a storm into a barn. Nice girl right? Well what was she doing with an extra horse? Thank you!
She was ponying the second horse. Since you can only ride one horse at time, and you have two horses to exercise (or a 2nd horse to train), you can take the second horse along with you ... it's called "ponying".
Good luck with your book and welcome to the forum.
She could be riding her experienced horse to help an inexperienced horse to give it confidence.
She could be riding from her pasture back to the barn.
She could be running away and taking her horses with her.
