Colorado's live mascot Ralphie VII makes her debut at Folsom Field in front of cheering crowd

The most anticipated run of the night — maybe even in Colorado's recent history — was turned in by a 700-pound bison just before kickoff. The Buffaloes' live mascot Ralphie VII made her debut Saturday night at Folsom Field in front of a roaring crowd. The 1-year-old bison didn't disappoint, either, galloping from her pen in the end zone to the other side of the 50-yard-line before turning around and making her way back to her trailer.
