Any chance you are near The Gorge?
I'm kind of nutty about Mustangs, and I'm also hoping to bring more AND folks together in the PNW. The two go so well together I think.
If yours is, as I think it is, of the very spanish type, we could be related. Mine are Andalusians, likely related the first horses brought from Europe to this continent. They should know their relatives.
I have new acquaintances that are Kigers in Bend, OR.
There are plenty of Spanish horses in the PNW.
Here's one of mine (she's not swaybacked, she's just having an ecstatic out-of-body experience because I'm given her a deep body massage) :
Her mane and tail are growing out to a great huge bushy mass, rather like yours in the picture you posted.
Okay, your turn. MORE pictures please.
