Paul, maybe you ought to consider adding this or something like it to your training set ups. It is clear that it is a demanding concept from the results the competitors are having. I really do not think it matters if you do it in Cheraw, SC or somewhere in WA. I was fortunate enough to train with someone that saw the value in exposing me and my dogs to the set up. As I was saying, it is eye opening to see how very different this is in real life than the way it looks on the net.
