She's awesome! I love how you're able to be so relaxed with her around barrels. She's not trying to get ahead of you at all. She seems very willing and I see no attitude. My girl tends to have a little bit of attitude if I try to keep things slow. And wow. 16.3!!!! My mare is 16.1 and 1100lbs and seems huge compared to most barrel horses. Is she like a giant rocking horse when you lope her? That's what I feel like when I ride my mare, but people usually let that rocking horse lope fool them. If I even lean slightly forward and slide up my hand after that third barrel it's game on and you better be ready or you're still sitting at that third barrel except in the dirt. LOL!
