Waste of money. Around here we have so many wild horses it is legal to feed them. They get into your trash if your neighbor hood does not have a wall around it. Really. They are everywhere. If you want one just come to NV with a rope.
Yeah horses are great but wild ones are just that, wild animals. Tens of thousands to save what announce to a pest? Silly. Would you spend that much to save an injured deer?
I guess that’s why some people like onions and some don’t. I have rescued many animals throughout my life. Some were domestic and some wild. I did not discriminate, because they are all G-d’s creatures.
