I am but a humble Longhorn fan, primarily a lurker at the famed Barking Carnival. I come to your site today as an admirer of your Farmageddon rivalry. Not just its glorious name, but everything it entails. Yours is an agricultural battle that is destined to end all agricultural battles--but the tragedy is that the battle will renew annually. The Farmageddon has the stuff of legend and it should possess the greatest rivalry prize in the land.
I do not mean something like the infamous Cy-Hawk Trophy.
No! What I propose is something that a winner would be happy to possess and a loser too might also take some pride in. Not a trophy, nor a mere governor's bet... but a yearly tribute! In times of yore, a weaker state would stave off the stronger by paying up a yearly tribute. In this case, the loser of the Farmageddon would surrender a small plot of land to the opposing school. Agriculture students from the winning school would sow the loser's plot with a desired crop, and agriculture students from the losing school would tend the crop for the year.
A year later, in the week before the game, the students would harvest and present the fruits of their labor as tribute to the victor.
There are many logistics to handle. This idea is but a seed, my own tribute to you and your unending wit. I leave it to you to contact Bring On The Cats and the agriculture departments from your respective universities.
(H/t reddit: Several months ago I was chastising Nebraska fans for trying to take the name Farmageddon, and a discussion broke out that suggested something like this yearly tribute.)
