A few years back, St. Henry had a great baseball tournament called the Redskin Classic. They played 3 other teams who were the Redskins. It's a great idea, and one I think would be really cool as a wrestling, track, or cross country meet. Some sort of Bulldog, or Eagle, or Tiger, or whatever meet, with only schools with that mascot.
I've also always thought it would be great to have a softball tri-match between all the Springfield's or Crestview's on one Saturday, just to hear the guys on the news say "In game one, Springfield beat Springfiled 11-5, while in the 2nd game, Springfield took down Springfield 7-3."
