Another thought to the "Pro Slaughter" thing. I find it unfortunate that so many of the rescues fill themselves up with horses that are no longer ridable. I am not saying they are any less worthy of care. It just seems sad that so many people want horses but so many great, ridable, young horses go to slaughter while rescues are full of older, un-ridable horses.
Again, in the perfect world, we would have places for all of them but until people get smart and STOP BREEDING BACK YARD HORSES we are going to have large numbers being slaughtered, through no fault of their own.
