Well If I know that I have to cross a stream, I need to think about it. See my lady has a thing about water, i'm not sure why she has but she has. When we cross we jump, first time she did that I was not ready. It is a good thing that I have ridden all my life and knew how to recover. I had only had her for about 2 month's at the time.
I only deal with brooks in the winter and spring and I limit her jumping as much as I can because of her knees. But I know that she loves jumping and so do I. So once a year I ride out the riff zone trail where we cross a stream once out, once back.
