I don't have any personal experience with that book but I have heard from several people on here that Beth Moore is a crock. IMHO, some horses are just not meant to have long hair, whether by genetics or environmental factors. Some horses are just naturally hairy while others have nothing at all. :(
Well I wnt to that barn today. The farrier was there so now her feet are very pruty. I finaly brushed her mane ( I never do because I want it to grow out) and low and behold it is thicker than I thought. I lied I'm sorry. :P well I guess we will see how long it takes to grow out. I'll send pics when its not raining.
Really, I think the best thing that you can do is to keep it clean and conditioned. Wash it once every couple of weeks, use a good leave in conditioner and put it up in loose braids or a mane bag. Don't every brush it, just pick out any knots with your fingers and keep her somewhere that there is nothing it can get caught on like a stall or a treeless paddock. I personally think that Sonador is beautiful and she doesn't need one of those big heavy flowing manes. I have several of those and the care is more than it is worth sometimes.
She lives in a treeless pasture. She has a run in and she is by her self all day and has a buddy at night. But they just keep there distance from each other. So I don't have to worrie about him pulling it out. :) I'd don't really want it for looks as much as I'm doing it so I can play with it. :P I love playing with long manes.
I'll loan you one of mine. How about Koda's? His averages about a foot and a half long (to the point of his shoulder) and I have to brush out knots and witch's stirrups every time I am out to see them.
