So you're a rescue, huh?

Some 501(c)(3) horse rescue in Oklahoma has this mare up for sale...with her colt at side by a registered AQHA stallion. What are they doing, trying to breed their own future rescues? This mare is as long as Britney Spears' hair extensions. She's downhill, short necked, crooked in front and post legged behind. She isn't a terrible horse but she isn't a breeding quality horse. And then they choose to breed her to a Quarter Horse with no show or race record. Why? Why? Why?
