I believe the sorrel horse on anything to do with AQHA is what was supposed to be the "perfect Quarter Horse"
I read that bit of information somewhere.
I just have to share my mares similarity to that horse...
Don't mind her fatness... but she even has the back socks.
Now, as for disposition wise:
A horse that can:
Be loaded into the trailer at 6am
Trailered on the gravel roads to a pasture round-up,
Tackle deep coulees and rocky hills with ease
Kick it into high gear over the rough terrain to cut off some cows
Sort cows from calves in the branding pen
Drag calves all day
And still have plenty of gas left to clock a smokin hot time on barrels
And then do it all again the next day.
That's what I like, anyway.
