Looks like the Peach State Marching Festival (one of the largest in GA) will be held next Saturday. I haven't seen a list of participating bands yet.

Thank you Jeff.
Your title should be "DCP Whisperer" which is sort of like Ghost Whisperer or Horse Whisperer but attune to what is actually being said on here.
My opinion:
Texas
Indiana
California
Oklahoma
Illinois
After that, 5-10 are a bit more difficult to list.
Florida and Ohio have a few really good groups. Kentucky and Michigan both also hold up pretty well. To round out the top 10, maybe Missouri?
