What's the Border War trophy?

Bronze Boot: started in 1968 by the schools' ROTC detachments, it's a combat boot worn in Vietnam by Capt. Dan J. Romero, an Army ROTC instructor at CSU.

How did the Border War start?

The first meeting, on Thanksgiving Day 1899 in Laramie, went to Colorado Agricultural 12-0 by forfeit after an argument between officials turned into a brawl. The campuses are about 65 miles apart on US 287, and before each game ROTC cadets carry the game ball in a relay to the state line, where the home team's detachment takes it the rest of the way. It's the oldest and most-played series in the Mountain West, and the schools were conference rivals in the WAC from 1968 to 1999 and in the Mountain West from 1999. Colorado State left for the Pac-12 in 2026.
