Mr. P's Palace.....................
Tell me the venue in STL that is able and willing to host Championships.
If you truly believe that there are "plenty of STL schools like would like to host" these shows and regionals, it's you that are the one fooling themself. Do you really think that this process consists of school after school lobbying to have a show at their site, only to be denied by MCCGA? More often than not, they have to go asking....and then they have to keep asking after they first person they asked declines.
Go to a meeting sometime and actually learn about some of the issues that this activity faces on a year to year basis before you start shooting off about the STL getting slighted or something like that.
