I am thinking about buying another horse for mostly trail riding, also maybe put it in some showing and speed events. I am looking at several horses. I came across a 9 year old Paint mare that I fell in love with its looks and how the owner described her. I also came across a 16 year old Paint mare, I haven't seen pictures yet but I like the description of the horse. They are both broke horses according to the owners, but the only thing that worries me about the 16 year old is her age. I know that isn't old for a horse yet but I wonder about the speed events and other things I might put her in. Any thoughts? They're both around the same price but the 16 is registered I think.
