Green broke I think has a pop up definition for it. Usually its been under saddle or been to a trainer for 90 days so it knows the basics.
Husband broke is a new one on me I imagine it means its broke for a beginner rider.
Dead broke is suppose to mean its bomb proof or that its never ever going to act up or spook. To me there is no such thing as a "dead broke" horse unless its actually dead
I wondered this before too. Sorrels have manes and tails that are of a lighter colour than their bodies (almost yellowish). Sorrel isn't as rich and reddy as a chestnut. It's more orangey-brown or light brown.
Correct me if I'm wrong. :P
I always thought luke was a light sorrel mix with pal. or champion color but I deff. think he a light sorrel it just the way the sun touch or anything that reflex his color. sometime in the early morning he look like if he almost pal. when he really isn't a pal. he just a very light sorrel color horse.
