The schools listed by Mr. Salyer have good followings, no doubt. But, it was my observation in the late 80's when Norton was 4A and again in 2002 when we were 4A that the majority of spectators at the 4A-5A-6A state tournament were from the 4A schools.
It will be interesting to compare the KSHSAA's financial reports of the Salina and Wichita tournaments. It should be a fair comparison in that 4A encompasses 64 high schools and 5A+6A also totals 64 schools. (Am assuming that all of these schools wrestle, but this os probably not correct.)
A further comparison of receipts of the 2006 5A+6A tournament to previous years' 4A-5A-6A Wichita could be also be enlightening (if weather this year is not a negative factor.)
to this discussion.
