Our 2011 son (of/pitcher) attended last year's camp in Atlanta. It was a great experience all the way around. Very organized, great staff, and lots of valuable information. Cannot say enough about the people who were running the camp. They seemed very genuine and put the kids (and parents) at ease. Based on our experience, they tend to focus more on the rising seniors so your son would probably get even more out of it. While they do offer instruction as part of the camp, we found the benefit to be more in the overall pro tryout experience. It is a great way for younger kids to get their feet wet and see what it is all about. For older kids, it is good exposure. It is the first camp/event we have attended where the scouts in attendance were as advertised. As far as the weather, having lived in Georgia my whole life I can tell you it will be hit or miss in December. Last year it was cold and a little rainy but it didn't take away from the overall experience. Hope this helps. Let me know if you have any specific questions.
