I agree with the thoughts of 24/7. The word, "Nationals" seems to have a diminished meaning these days. Just like being an "All-American" has lost certain luster.
Before you know it, there will be a "Champ of the Universe" or an "All-Inter-Galactic!"
My basic thoughts are that there's no way a tournament can claim they are a National tourney unless there is a legitimate qualifying. (not just signing up)
