If it's distracting you from writing a good story, it's too distracting. But do whatever works, of course. Of all the books I've read, I can only remember the chapter lengths for two: one because I found it interesting (Tamora Pierce's Immortals books are ten chapters each), and one because the chapter length (a page and a half) annoyed me so much I almost stopped reading. Though that wasn't the only thing wrong with that book...
Did a little research on dude ranches for BB. And...I think I might have to scrap this one completely and start over.
WAIT. I have an idea. I think I've finally got it...
