 So, the calcide foot is going to be whichever foot is closest to the cow at the time. Today we're going to work the flag, so right now if I said her calcide foot, that's going to be my right leg. And we're going to talk a little bit about maybe what it's for, when somebody would tell you to use it, and how it can help you. Okay, so what about the herd side foot? Now the herd side foot, like I said, today we're working the flag, so this is going to be the herd side foot. Today is going to be the left, the herd is going to be back here and we're working the flag on our right, so this left leg is going to be herd side. So, Taren, can you work the flag and demonstrate while when you use the cow side foot and why you use it, and then you'll use the herd side foot. Just give a demonstration of how it can affect the cow and the horse. Right now, my right leg is herd side, I can use it right there, I can use it for a couple different reasons. Typically, when I use herd side, I'm going to try and hold my horse up, which means if we were coming across here and they fall away like so, I'm going to put my herd side on her and try and drive her up here, try and push her right out here, same deal coming this way if she was to fall off, so I'm going to put my left leg on her or herd side and drive her right back up here to where she needs to be, keep a hold to the cow. Now, if she comes out of there and she's leaning on the cow here, I'm going to put my cow side leg on her and drive her away from it.
