This poor mare has been on CL for at least a couple of months. I have the feeling that the person who put up the ad is being very fussy as to where the mare is going to go, and hasn't found the 'right' place yet.
I can understand not wanting to let meat buyers have her, but...why not get a bridle and a saddle to check her out?
Did you notice in the last picture, the horse is almost falling over?
I hope someone who is local, will call these people and give them a 'Come to Jesus' speech. Also, tell them their ad is all over the net, with hundreds of thousands seeing it. Nobody is impressed. Just another form of animal abuse.
