It's simply stupid not to wear a helmet, even my instructor says "horses are unpredictable, even the quietest horse might spook and you should always be paying attention and reading your horse, but you should wear a helmet anyways!" And have I got a story for you to back me up on that:

At my old instructors place they rescused a lot of horses and two were Parelli-trained and apparently the kid didn't have a clue what he was doing so he really messed them up! When we were retraining Shelby (my favorite) my instructor was lunging and I was riding to get her used to having contact on the bit and things. It was about the middle of winter in Canada so there was quite a bit of ice on the ground. As I slowly asked Shelby for the bit just collecting the reins and squeezing lightly with my legs she freaked and took off into a canter and as she came around the icy patch she slipped sending me underneath her and she landed on my head. She got up pretty quickly and took off again but the doctor had said if it weren't for my helmet I sure as h-ll wouldn't be here!

My point is how helmets are nessicary for one, but also how easy it is for people to mess up the system. My new instructor and I were working on Parelli together when I realized how pointless it all was. Any good horseperson could've invented the system and it's all made up. Sorry if I seem harsh on PP but I'm a bit p'od that I wasted so much on his system. And so if it's all invented then clearly something will go wrong. What if horse doesn't do B when you do A? Then you're stuck in Level 1 Forever? I love my horse so instead I've been using TTOUCH before my lessons and we're going to try bridleless riding so he is happier but I'm not going to toy around with pointless exercises.

Am I making any sense? Sorry, I feel like I'm rambling on!

"People may tell me that they are great riders, fantastic horsemen, or knowledgeable horsepeople. I never believe them until I speak to their horses."

When it comes down to it, horses are unpredictable and it's not always even your horse(s) that you have to worry about.  You can be injured if someone else loses control of their horse.  Another horse could collide with yours or just spook yours.  Horses are herd animals and tend to want to follow what others are doing, especially if they are inexperienced.

*Lady mounting her horse from a mounting block witouth helmet, One foot on her stirrup, she was ready to jump right up when horse spooked. she fell backwards and hit her head with mounting block. *

*My trainers friend after exercizing the horse takes them to cool of at this short nearby trail, the horse was being walked and all of a sudden it tripped rolling donw hill with his rider on. he had a helmet on, and unlike many riders , he didnt take it off to cool his horse down. alot of riders tend to take helmets off when their done with lesson, but still on their horses*

Theres no such thing as parelli being 100% secure, and there's alot of people out there who flip the momment they hear that parelii can still be dangerous.
