In 1968, the ROTC detachments of the respective schools initiated the Bronze Boot, a traveling trophy awarded to the winner of the “Border War” each year. The boot was worn in the Vietnam War by Cpt. Dan J. Romero, an Adams State College graduate and Army ROTC instructor at CSU between 1967 and 1969. Each year leading up to the Colorado State–Wyoming game, the game ball is carried in a running shuttle relay by the ROTC detachment of the visiting team along US 287 to the Colorado–Wyoming border, where the home team's ROTC detachment receives it and runs the game ball to the stadium hosting the game. The trophy is guarded by the ROTC unit of the past year's winning school during the game.
The "Border War" between Colorado State and Wyoming also extends to men's basketball. The ESPN College Basketball Encyclopedia considers Colorado State to be Wyoming's "fiercest rival". Wyoming has a 131–92 series lead over Colorado State as of January 7, 2015.
