March 25, 2015 - One of the wildest, most spirited and extremely heartwarming RodeoHouston® events is the Calf Scramble. With the drop of a cowboy hat, the calves are signaled to be released onto the dirt arena for 30 Texas 4-H and FFA members to chase and catch using only a rope halter. The number of students is always greater than the number of calves. With teenagers and calves darting in every direction across the NRG Stadium floor, the calf scramble is one of the most chaotic, unscripted and beloved events of the Rodeo.
