Watching Cathy Jo and her horse Petey lead the Broncos onto the field is more than just a game-day tradition—it’s a full-on community effort! From the Petey Posse glamming up Petey’s mane with blue and orange extensions to Cathy Jo’s mom running the show behind the scenes, every home game is a labor of love. Cathy Jo, who’s dreamed of this role since she was seven, says the energy at championship games is next-level. Meeting fans, waving to kids, and sharing stickers are just as important as the run itself. What’s your favorite Bronco Girl memory or tradition? #Sports #Football #BoiseState
