I won't tell you how to write your story... but I will say I am grateful you are doing some research. There is a successful (in that she has sold a lot of books) Romance Novelist who writes about horses, racing and Kentucky horse farms and from her writing it is clear she has no idea which end of the horse takes feed in and which end of the horse evacuates the feed after digestion!
Total unmitigated crap.. and I find it hard to believe she is a published author. She must have known somebody to get that far because she most assuredly knows nothing about horses, racing or horse farms!
There is something about the outside of a horse that is good for the inside of a man. ~Winston Churchill
