Randy, I will guarantee you, even if you shorten the season some club will eventually begin holding folkstyle tournaments on those weekends immediately following. In fact those weekends of high school regionals and state (as some clubs already know), would be perfect for some club to make a bunch of money because they don't have other tournaments to compete with. And in turn, most if not all clubs will support these tournaments, just as they do now.
I have been rather surprised that some club locally hasn't already tried to hold a folkstyle tournament during the heart of the freestyle season. As Ottawa (with the 6U state) and others have proven, if there is money to be made out there, someone will do it.
I don't think it will do any good to adjust our season until we have the hearts and minds of the majority of our parents/coaches/club directors all thinking alike.
