If its sunny... Id leave her tied in the sun till she dries.
I have appaloosas that are impossible to keep clean. And in the winter before shows need bathed. I bathe them as quick as possible, sweat scrape them, then walk them in the sun. Once they are about half way dry.... I throw their blanket on and put them in their stall.
Many people have sighed for the 'good old days' and regretted the 'passing of the horse,' but today, when only those who like horses own them, it is a far better time for horses. ~C.W. Anderson
