Larry Fields did a breaking seminar for first time breakers at my school last Saturday. It was primarily for the kids, but we adults got to do a few breaks, also. It was a lot of fun, and Mr. Fields did a great job with both the kids and the adults. This was my first time breaking (I had broken rebreakables a couple of times, but never real boards), and I liked the way it required focus and accuracy. I think I may have to do more of this.
