I'd have to say Mares for Me!!! My mare would decide she wouldn't want to be ridden and wouldn't work, so we'd have to ride longer until she decided to shape up, but we were a TEAM on days when she was in a good mood!!! And I'll agree that they are really great around kids! She didn't really like her nose petted, but with this one girl at my barn, she would drop her head and the little girl would hug it!!! I like the challenge also, lol. I tend to get one too broke and have to sell/trade for something I can break when I have geldings. My mare would pitch a fit some times and I think we both loved it!
