Ok, I have a question.  I have taken martial arts in the past, but have since moved and not found a school yet.  I still go over my current and past techniques, forms, etc.   I am a youth leader for our high school kids and want to do a sermon and use karate has an attention getter.     However, one thing that was never taught to me was how to break boards.  I would like to incororate the sermon and breaking of boards, but I know zilch about it.   What type of boards?  How I do hit it?  Etc.   Thanks!
