I hear ya HC.
I stopped after a very close friend got killed riding bare back.
He got thrown opposite of his riding hand and got hung up.
The horse went down the fence and his head bounced of 7 or 8 poles.
Broke his neck and ripped part of his skull open on a bolt that was left sticking out to far.
When I left the arena that night I walked off with nothing but my hat. I left my gear and bag on the ground behind the chutes, never to ride again.
I learned better than that years ago, been chased upon a pickup, a gate, over a fence by plain old "brimmer" (Brama) cows with a baby calf. More'n once. They and their male partners can gut a horse real quick. And you too if on foot.
I rode a few back when I was dumber. It was a blast and I loved it. The Hospital bills weren't all that fun. I've seen the wrecks and the money and there is a lot more wrecks than money. All this said, the guy knew what he was getting into before he did it. If you don't plan on getting hurt, stay away from bulls. Like High caps friend found out, even the little one can hurt you. Sorry to hear about the injured cowboys from both Madmo and Highcap.
