I'm not familiar with "horse tripping" and do not believe I wish to become such! As for rodeos, I've been to quite a few in my day...growing up in AZ it's fairly cultural (we even have "rodeo beak" here for the kids in school in the spring, in addition to spring break!)...
The worst thing I can recall seeing I had to see VERY UP CLOSE AND PERSONAL. My BF at the time was a paramedic and he signed up to do a lot of the "standby's" (the EMS on-scene providers for sporting events) so he could enjoy the show, get paid, and often get some good traumas out of the deal (EMS workers consider traumas "good" in the sense that they get to brush up on their skill set and learn from the experience, not because people are getting harmed, of course!!)...anyhow...to make a long story short (er), a bull rider was gored through the TESTICLE and as a result, the entire, um, testicular "sac" was ripped open and he lost the testicle to that horn (the rack tips were obviously not sawed off of these bulls) and since I, as the GF, was doing a "ride-along" with their unit that night, I was in the rig as the guys transported the unfortunate cowboy to the closest ER "code three" (lights/sirens) & that poor dude literally SCREAMED HIS LUNGS OUT UNTIL HE WAS HOARSE the whole way, even after the IV was in and he received 10 mg morphine IV over the twenty minute transport. He also bleed like a, well, stuck 'cowboy'(?) Ha...very poor taste joke at the end...apologies.
The creepy part was the fellow bullrider who had to pull his buddy's testicle and shredded sac pieces from the horn if the bull where it continued "dangling"!
My BF followed up and actually visited the dude, just to see that he was alright. He did have reconstructive surgery and they sutured the remaining sac back around around the remaining testicle.
The rider was quite lucky actually. If the bull had gored him just a little to one side or the other, he would likely have had his femoral artery severed and bled out in seconds, literally. That or an abdominal puncture, leaving him with peritonitis, or missing part of his gut long term and possibly even with a temporary colostomy! A dude can live with only one testicle, but bit without any blood, and not with a horrid abdominal infection from the contents of the bowel spilling into the abdomen (peritonitis)...he was lucky overall, thus!!
Sorry for my über-grody story! ;0)
