There are several pictures/videos on you tube of cattle being ridden and trained to do tricks. Some have some great personalities.. was a guy here in this area that used to ride his brahman steer in parades.
I found some of those videos while looking for some instructional videos. Pretty neat for sure.
Even found PremierLonghorn in my home state that specializes in raising and training saddle and trick longhorn. Maybe one day my Zebu will be on there.lol
