She's honest and puts the horse first. She's not one to baby you or make you feel good as a rider or help you look good for the audience. She's there to improve your performance and your horse's performance and if you want to improve, you'll get a lot for your money. I'd heard that she was brutal but I found her kind and fair, clear, and funny. She's great honing in on whatever issue you're having or what you'd like to improve, and she's got great exercises to help with whatever issue you're having.
The aids are the legs, the hands, the weight of the rider, the whip, the caress, the voice and the use of extraneous circumstances. ~ General Decarpentry www.reflectionsonriding.com
Sorry, but wearing a hat is a personal decision. Don't miss good instruction for an issue that only affects each individual. Therefor do not take a clinic with any European rider, because most will not wear helmets. By the way I am a helmet supporter, but just get the best training you can get when it is available.
