Kelley,
I haven't been to his school, but I have learned a lot about shooting from him personally over the last dozen years. From every account, his shooting schools are going well and I have yet to hear of anybody who hasn't benefitted from them. You'll learn a lot of things that you can't pick up in a vidoe or book, and you will have an opportunity to review each step of your form with arguably the best traditional shooter of our time. For the minimal cost, you can't go wrong.
Email Jon Simoneau about his experience. He learned more in one weekend about proper shooting form than he had picked up his entire shooting years.
Best wishes, Brady
