Cattle penning is a rodeo event where a team of three is given one minute to cut three cattle from a herd of many and then to drive them into a sorting pen. Each cow in the herd has a numbered tag on its back and only when the judge's whistle sounds is the team given the numbers of the three animals it must cut and pen.
Thanks everyone for your comments. Cattle penning is a traditional event among ranchers and many are older than some in other events since their lifetime of experience and savvy chasing cows makes them often the best competitors.
