They are removing hoses: http://www.habitatforhorses.org/blm-to-remove-4800-wild-horses/
We’ve been past the big corral north of Reno and to see all the hundreds of horses there with absolutely no shade is pretty sad. They get food and water but there’s no place for them to escape the sun in the summer. At least when they are roaming out on blm land they can find a gulley or a wash or outcropping to get out of the sun.
